included from 'ac/withenable.ac' and 'configure.ac'.
+ Usually, the new program is maintained somewhere outside of TeX Live.
+In that case, we put the upstream sources into a subdirectory 'PROG-src'
+(e.g., 'utils/newprog/newprog-src'). We do not run 'configure' in this
+original '...-src' directory, only in our own directory, but we do
+compile using the source files in '...-src'.
+
+ So, these are the files that we must generally create:
+
+'ac/withenable.ac'
+ The 'KPSE_ENABLE_PROG' call just explained.
+
+'configure.ac'
+'Makefile.am'
+ By merging the contents of the original 'configure.ac' (if

+ recipe, it's necessary to think about needs to be done in the
+ original vs. in TeX Live.
+

+ Actions taken after getting the original source tree; typically
+ removal of derived or unused common files.
+
+'TLpatches/patch-...'
+ If any changes are needed to the original sources, record the
+ patches here so they can be applied next time. And send them
+ upstream so that perhaps they won't have to be.
+
+'ChangeLog'
+ Record all TL-specific changes, now and in the future.
+
+ Then, run GNU 'autoreconf' in the new directory (*note Build system
+tools::). After that works, 'svn add' the necessary files, notably
+'Makefile.in aclocal.m4 configure', and 'svn:ignore' the Automake cache
+'autom4te.cache'. (This is so people checking out the TL source tree do
+not have to run any autotools, but can simply run 'configure'.)
+
+ Then, run the TL tool 'reautoconf' in the top-level TL 'source/'
+directory, to incorporate the new program into the build tree.
+
+ Then, run (and rerun) a build until the program compiles and tests
+successfully, probably involving rerunning autoreconf in the source
+directory, 'make' in the build directory, etc.
+
+ After final success, don't forget to commit.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+MANUAL INSTALLATION of axohelp v. 1.1 and axodraw2
+==================================================
+
+
+
+A. Fully Manual Installation
+----------------------------
+
+ Note: if you do not wish to use axodraw2 with pdflatex, xelatex, or
+ lualatex, but will only use it with latex, then only the
+ first step is needed.
+
+ 1. Copy axodraw2.sty to a suitable directory for LaTeX style files.
+
+ 2. Compile the axohelp program by a command line like
+
+ gcc -o axohelp -Wall -O3 axohelp.c
+
+ (The exact details of the command line depend on your operating
+ system and which compiler you have installed for the C
+ language.)
+
+ 3. Move axohelp to a suitable directory for executables.
+
+ 4. (Optional) Copy axodraw2-man.pdf to a suitable directory for
+ LaTex package documentation.
+
+ 5. (Optional) Copy axohelp.1 to a suitable directory for man pages.
+
+
+B. Using autoconf etc:
+---------------------
+
+ You can also make axohelp using the GNU utilities autoconf,
+ automake and autoreconf (if these are installed). Doing this is
+ enormous overkill for a program like axohelp with a single source
+ file and with no need to make adjustments dependent on the
+ operating system etc. Even so, we provide the files necessary for
+ the use of autoconf and automake, since these are needed when the
+ axodraw2 package is incorporated into TeXLive (which has an
+ enormous automated build process). So here are the instructions
+ for building with autoconf and automake. For these, it is assumed
+ that the GNU utilities autoconf, automake and autoreconf are
+ installed:
+
+ As in Fully Manual Installation, but replace step 2 by
+
+ 2'. Run
+
+ autoreconf --install
+ ./configure
+ make
+ make check
+
+ The last line runs a test to ensure axohelp is running
+ correctly.

+Axodraw2 is a package that defines macros for drawing Feynman graphs
+in LaTeX documents.
+
+It is an important update of the axodraw package, but since it is not
+completely backwards compatible, we have given the style file a
+changed name.
+
+Many new features have been added, with new types of line, and much
+more flexibility in their properties: For details see the
+documentation.
+
+In addition, it is now possible to use axodraw2 with pdflatex, as well
+as with the latex-dvips method. However with pdflatex (and also lualatex
+and xelatex), an external program, axohelp, is used to perform the
+geometrical calculations needed for the pdf code inserted in the
+output file. The processing involves a run of pdflatex, a run of
+axohelp, and then another run of pdflatex.

+%=========================
+\section{Introduction}
+\label{sec:intro}
+
+This is the documentation for axodraw2, a \LaTeX{} package for drawing
+Feynman graphs (and other simple graphics). This is version 2 and a
+substantial update of the original axodraw package \cite{axodraw1},
+which was released in 1994, and which has become rather popular in the
+preparation of articles in elementary-particle physics. One of its
+advantages is that its drawing primitives are included in the
+\file{.tex} document, in a human-writable form. (This also allows
+convenient production of axodraw figures by other software, e.g.,
+Jaxodraw \cite{jaxodraw1,jaxodraw2}.) This is in distinction to
+methods that use a separate program to create graphics files that are
+read in during the processing of the \LaTeX{} file. The objects
+needed in Feynman graphs are often difficult to draw at high quality
+with conventional computer graphics software.
+
+The original axodraw package has hardly been modified since its
+introduction. The new version addresses several later needs. A
+detailed list of the changes is given in Sec.\ \ref{sec:changes}.
+
+One change arises from the fact that \TeX{} (and hence \LaTeX{})
+itself does not possess sufficiently useful methods of drawing
+complicated graphics, so that the drawing of the graphics is actually
+done by inserting suitable code in the final output file (postscript
+or pdf). The original axodraw worked only with the
+\program{latex}-\program{dvips} processing chain to put the diagrams
+in the final postscript file.\footnote{A pdf file can be produced from
+ the postscript file by a program like \program{ps2pdf}.} Now we
+also have in common use the \program{pdflatex} (and \program{lualatex}
+and \program{xelatex}) programs that directly produce pdf. The new
+version of axodraw works with \program{pdflatex}, \program{lualatex},
+and \program{xelatex}, as well as with the
+\program{latex}-\program{dvips} method.
+
+Furthermore, more kinds of graphical object and greater flexibility in
+their properties have been found useful for Feynman graphs. The new
+version provides a new kind of line, B\'ezier, and is able to make the
+various kinds of line doubled. There is now a very flexible
+configuration of arrows. Many of the changes correspond to
+capabilities of JaxoDraw \cite{jaxodraw1,jaxodraw2}, which is a
+graphical program for drawing Feynman graphs, and which is able to
+write and to import diagrams in the axodraw format.
+
+Finally, substantial improvements have been made in the handling of
+colors, with much better compatibility with modern packages used to
+set colors in the normal \LaTeX{} part of a document.
+
+Since some of the changes (especially in the internal coding)
+introduce incompatibilities (Sec.\ \ref{sec:compat}) with the original
+version of axodraw, the new version of the style file is given a new
+name \file{axodraw2.sty}. Then the many legacy documents (e.g., on
+\url{http://arxiv.org}) that use the old axodraw will continue to use
+the old version, and will therefore continue to be compilable without
+any need for any possible changes in the source document, and with
+unchanged output. Even so, as regards the coding of diagrams, there
+are very few backwardly incompatible changes in axodraw2.
+
+The software is available under the GNU General Public License
+\cite{GPL} version 3.
+
+
+
+%=========================
+\section{Changes}
+\label{sec:changes}
+
+\subsection{Changes relative to original, axodraw version 1}
+\label{sec:changes.wrt.1}
+
+Relative to the original version of axodraw, the current version,
+axodraw2, has the following main changes:
+\begin{itemize}
+
+\item A bug that the line bounding an oval did not have a uniform
+ width has been corrected.
+
+\item A bug has been corrected that axodraw did not work with the
+ revtex4 document class when \verb+\maketitle+ and two-column mode
+ were used.
+
+\item Axodraw2 works both when pdf output is produced directly using
+ the programs \program{pdflatex}, \program{lualatex}, and
+ \program{xelatex}, as well as when a postscript file is produced by
+ the \program{latex}--\program{dvips} method. The old version only
+ worked when postscript output was produced. However, an auxiliary
+ program is needed when using \program{pdflatex}, \program{lualatex},
+ or \program{xelatex}. See Sec.\ \ref{sec:doc.compile} for how this
+ is done.
+
+\item In the original axodraw, a diagram is coded inside a
+ \verb+picture+ environment of \LaTeX. Now, a specialized
+ \verb+axopicture+ environment is provided and preferred; it provides
+ better behavior, especially when diagrams are to be scaled.
+
+\item In association with this, there are some changes in how scaling
+ of diagrams is done.
+
+\item An inconsistency in length units between postscript and \TeX{}
+ has been corrected. All lengths are now specified in terms of
+ $\unit[1]{pt} = \unit[1/72.27]{in} = \unit[0.3515]{mm}$. Previously
+ the unit length for graphics was the one defined by postscript to be
+ $\unit[1]{bp} = \unit[1/72]{in} = \unit[0.3528]{mm}$.
+
+\item Substantial improvements have been made in the treatment of
+ color. When named colors are used, axodraw2's use of color is
+ generally compatible with that of the modern, \LaTeX-standard
+ \file{color.sty} package. It also provides all the color-setting
+ macros that were defined in v.\ 1 of axodraw, including those of the
+ \file{colordvi.sty} package used by v.\ 1.
+
+\item The various types of line can now be produced as double lines,
+ e.g.,
+ \begin{axopicture}(35,5)(0,-2)
+ \SetWidth{1}
+ \Line[double,sep=2.5](0,2)(35,2)
+ \end{axopicture}.
+ This is commonly used, for example, for notating Wilson lines.
+
+\item Lines can be made from B\'ezier curves.
+ Currently this is only for simple lines, not photon, gluon, or
+ zigzag lines.
+
+\item Gluon, photon, and zigzag lines can be dashed.
+
+\item Macros are provided for drawing gluon circles, without the
+ endpoint effects given by the corresponding gluon arc macros.
+
+\item The positions and sizes of arrows can be adjusted. See Sec.\
+ \ref{sec:arrows} for all the possibilities. One example is
+ \begin{axopicture}(30,6)(0,-2)
+ \SetWidth{1}
+ \Line[arrow,arrowpos=0.8](0,2)(30,2)
+ \end{axopicture}
+
+\item Macros for drawing polygons and filled polygons are provided.
+
+\item Macros for drawing rotated boxes are provided.
+
+\item A macro \verb+\ECirc+ is provided for drawing a circle with a
+ transparent interior.
+
+\item A macro \verb+\EBoxc+ is provided for drawing a box with a
+ specified center.
+
+\item A macro \verb+\AxoGrid+ is provided for drawing a grid. One
+ use is to provide a useful tool in designing pictures.
+
+\item Since there are now many more possibilities to specify the
+ properties of a line, optional arguments to the main line drawing
+ commands can be used to specify properties in a keyword style.
+
+\item A new macro named \verb+\Arc+ is introduced. With the aid of
+ optional arguments, this unifies the behavior of various arc-drawing
+ commands in the original axodraw.
+
+\item For consistency with the \verb+\Gluon+ macro, the
+ \verb+\GlueArc+ macro has been renamed to \verb+\GluonArc+, with the old
+ macro retained as a synonym.
+
+\item The behavior of arcs is changed to what we think is more natural
+ behavior when the specified opening angle is outside the natural range.
+
+\item What we call macros for drawing objects with postscript text are
+ now implemented within \LaTeX{} instead of relying on instructions
+ inserted in the postscript code. Thus all the normal \LaTeX{}
+ commands, including mathematics, can now be used in all text
+ objects, with proper scaling. The placement and scaling of text
+ objects are more consistent.
+
+\item Some new named colors are provided:
+ \LightYellow{LightYellow}, \LightRed{LightRed},
+ \LightBlue{LightBlue}, \LightGray{LightGray},
+ \VeryLightBlue{VeryLightBlue}.
+ (LightYellow, LightRed, LightBlue, LightGray, VeryLightBlue.)
+
+\item The macros originally specified as \verb+\B2Text+,
+ \verb+\G2Text+, and \verb+\C2Text+ are now named \verb+\BTwoText+,
+ \verb+\GTwoText+, and \verb+\CTwoText+. The intent of the original
+ code was to define macros with names \verb+\B2Text+, etc. However
+ in \TeX, under normal circumstances, macro names of more than one
+ character must only contain letters, unlike typical programming
+ languages that also allow digits. So the rules for \TeX{} macro
+ names mean that in defining, for example
+ \verb+\def\B2Text(#1,#2)#3#4{...}+, the original version of axodraw
+ actually defined a macro named named \verb+\B+, obligatorially
+ followed by \verb+2Text+. This caused a conflict if the user wished
+ to define a macro \verb+\B+. If it is desired to retain the old
+ behavior, then the following should be placed in the preamble of the
+ \file{.tex} file, then the axodraw2 package should be invoked in the
+ source document with the \texttt{v1compatible} option:
+ \begin{verbatim}
+ \usepackage[v1compatible]{axodraw2}
+ \end{verbatim}
+
+\end{itemize}
+
+\subsection{Changes relative to axodraw4j distributed with JaxoDraw}
+\label{sec:changes.wrt.4j}
+
+The JaxoDraw program \cite{jaxodraw2} is distributed with a version of
+axodraw called axodraw4j. At the time of writing (July 2016), this
+was effectively a predecessor of axodraw2, but without the possibility
+of working with \program{pdflatex}. (The suffix ``4j'' is intended to
+mean ``for JaxoDraw''.)
+
+The changes in axodraw2 relative to the version of axodraw4j dated
+2011/03/22 are the following subset of those listed in Sec.\
+\ref{sec:changes.wrt.1}:
+\begin{itemize}
+\item The ability to work with \program{pdflatex}, \program{lualatex},
+ and \program{xelatex}.
+\item The improvements in the handling of color and fonts.
+\item The double and arrow options for B\'ezier lines.
+\item The dash option for gluons and photons.
+\item Color option for all lines.
+\item Correction of inconsistency of length unit between \TeX{} and
+ postscript.
+\item Better drawing of double gluons and photons.
+\item Addition of the macros for making gluon circles, polygons, and rotated
+ boxes.
+\item Addition of the macros
+ \verb+\ECirc+, \verb+\EBoxc+, and \verb+\AxoGrid+.
+\item A series of ``LongArrow'' macros for drawing lines with the
+ arrow at the end. The same effect could only be achieved in
+ axodraw4j with arrowpos=1 option to the basic line-drawing
+ commands.
+\item A series of macros like \verb+\DashDoubleLine+ to provide access
+ to the dashed and double properties in the style of the macros
+ provided in v.\ 1 of axodraw. This is in addition to the optional
+ arguments that allow the same effect in axodraw4j and in axodraw2.
+\item The \texttt{v1compatible} and other options are provided for the
+ package.
+\item Better treatment of the scaling of objects.
+\item The treatment of ``postscript text objects'' within \LaTeX{}
+ itself.
+\end{itemize}
+
+
+%---------------
+\subsection{Backward compatibility, etc}
+\label{sec:compat}
+
+The official user interface of axodraw2 is backward-compatible with
+versions 1 and 4j, with the exception of the issue mentioned above
+about the commands that had the signatures \verb+\B2Text+,
+\verb+\G2Text+, and \verb+\C2Text+ in the old version.
+
+As to behavior, there are some minor changes in the objects that are
+drawn, mostly concerning the exact dimensions of default arrows. The
+scaling of the sizes of text objects is changed. The scoping of color
+changes is substantially changed, but improved.
+
+The old axodraw only used the tools available in \LaTeX{} in the early
+1990s. The new version needs a more modern installation.
+Installations for which axodraw2 has been tested include TeXLive 2011
+and 2016.
+
+We have tested backwards compatibility by compiling the version 1
+manual with axodraw2; only a trivially modified preamble was needed.
+It also worked to compile Collins's QCD book\cite{qcdbook},
+which has a large number
+of JaxoDraw figures (processed automatically to pieces of axodraw code
+imported into the document); only changes in the preamble were needed.
+
+In addition, axodraw2 provides an \verb+axopicture+ environment inside
+of which axodraw2's graphics are coded and drawn. In the old axodraw,
+\LaTeX's \verb+picture+ environment was used instead. In axodraw2, we
+recommend only the use of \verb+axopicture+ environment, and that is
+the only method we document. However, old diagrams coded with
+\verb+picture+ environment continue to work.
+
+Some possible compatibility issues could arise because the old and new
+versions load a different set of external packages. The old version
+loaded the packages \file{epsf.sty} and \file{colordvi.sty}, and so
+macros defined by these packages were available. The new version does
+not load these now essentially-obsolete packages; so they should be
+loaded from the document if they happen to be needed. But the new
+version does define some macros for setting colors that correspond to
+those in \file{colordvi.sty}; these are defined using facilities from
+the standard \LaTeX{} \file{color.sty} package. Axodraw2 loads the
+following \LaTeX{} packages: \program{keyval}, \program{ifthen},
+\program{graphicx}, \program{color}, \program{ifxetex}. It defines
+its own set of 73 named colors which are the 68 dvips-defined names
+(as coded in \file{colordvi.sty} and used in axodraw v.\ 1), plus 5
+more.
+
+
+
+%=========================
+\section{Installation}
+\label{sec:installation}
+
+%---------------
+\subsection{Installation from standard \TeX{} distribution}
+
+At the moment that this document was updated (January 2018), axodraw2
+was part of both the main \TeX{} distributions, TeXLive and MiKTeX.
+The easiest way to install axodraw2 is therefore from the package
+manager of your \TeX{} distribution. (There is one complication
+concerning the \program{axohelp} program --- see below.)
+
+You can also obtain axodraw2 from CTAN at
+\url{http://ctan.org/pkg/axodraw2}, and install it manually, following
+the instructions in Sec.\ \ref{sec:manual.install} below.
+
+\paragraph{\program{axohelp} in TeXLive}
+In TeXLive 2017, a binary executable for the \program{axohelp} was not
+provided, even though the rest of the axodraw2 package was provided.
+Thus you could use axodraw2 with the \program{latex} but not with
+\program{pdflatex} unless you compiled and installed the program
+\program{axohelp} yourself following the instructions below. This is
+planned to be changed in TeXLive 2018, when \program{axohelp} should
+be provided as part of the distribution when the package axodraw2 is
+installed from the package manager.
+
+\paragraph{\program{axohelp} in MiKTeX}
+The axodraw2 package including an executable \program{axohelp.exe} was
+provided by MiKTeX when this was checked in January 2018.
+
+
+
+%---------------
+\subsection{Manual installation}
+\label{sec:manual.install}
+
+%For a manual installation, the minimum that needs to be done is to put
+For a manual installation, what needs to be done is to put the file
+\file{axodraw2.sty} in a place where it will be found by the
+\program{latex} program. If you wish to use axodraw2 with
+\program{pdflatex}, you will also need to compile the
+\program{axohelp} program --- see Sec.\ \ref{sec:axohelp} --- and put
+it in an appropriate directory. Documentation can also be installed
+if you want.
+
+%--
+\subsubsection{Style file \protect\file{axodraw2.sty}}
+
+If you merely want to try out axodraw2, just put the file
+\file{axodraw2.sty} in the same directory as the \file{.tex}
+file(s) you are working on.
+
+Otherwise, put it in an appropriate directory for a \LaTeX{} style
+file, and, if necessary, run the texhash program to ensure that the
+file is in the \TeX{} system's database of files. For example,
+suppose that you have a TeXLive system installed for all users on a
+Unix-like system (e.g., Linux or OS-X), and that TeXLive is installed,
+as is usual, under the directory \file{/usr/local/texlive}. Then an
+appropriate place for axodraw2 is in a directory
+\file{/usr/local/texlive/texmf-local/tex/latex/axodraw2}. You will
+need to run the \program{texhash} program in this last case. For such
+a system-wide installation, you may have to do these
+operations as an administrative user (e.g., root), possibly
+supplemented by running the relevant commands with the \program{sudo}
+program.
+
+But note that if you later install the axodraw2 package from the
+package manager of you \TeX{} distribution, it's a good idea to delete
+the files you installed manually. Otherwise when you use axodraw2 in
+a document, then the wrong version of \file{axodraw2.sty} may get
+used. This is a particularly important issue after possible future
+updates to axodraw2 get installed by the package manager.
+
+%--
+\subsubsection{Helper program \program{axohelp}}
+\label{sec:axohelp}
+
+If you wish to use axodraw2 with \program{pdflatex}, \program{lualatex},
+or \program{xelatex}., then you need to install the \program{axohelp}
+program.
+
+On a Unix-like system (e.g., linux or OS-X), you first need to compile
+the program by a C compiler. An appropriate shell command to do this
+is
+\begin{verbatim}
+ cc -o axohelp -O3 axohelp.c -lm
+\end{verbatim}
+(Note that this is a C compiler, \emph{not} a C++ compiler.) Most linux
+systems have the program \program{cc} already installed. This also applies to
+OS-X at versions below 10.7. But on OS-X version 10.7 and higher, you
+will need to install a compiler, which can be done by installing XCode
+and the associated command-line utilities. If you have the GNU
+compilers installed, you might need to use the command \program{gcc}
+instead of \program{cc}.
+
+For Microsoft Windows, if you do not have a C compiler available, you
+can use the Windows binary \file{axohelp.exe} we have provided. It
+was compiled on Windows 10, and should work with at least that version
+of Windows.
+
+In any case once you have the executable (named \program{axohelp} on
+unix-like systems, or \program{axohelp.exe} on a Microsoft system), put
+it in a directory where it will be found when you run programs from
+the command line.
+
+
+%--
+\subsubsection{Testing}
+
+To test whether the installation works, you need a simple test file.
+An example is given in Sec.\ \ref{sec:example}, and is provided
+with the axodraw2 distribution as \file{example.tex}.
+
+At a command line with the current directory set to the directory
+containing the file \file{example.tex}, run the following commands:
+\begin{verbatim}
+ latex example
+ dvips example -o
+\end{verbatim}
+If all goes well, you will obtain a file \file{example.ps}. When
+you view it, it should contain the diagram shown in Sec.\
+\ref{sec:example}. You can make a pdf file instead by the commands
+\begin{verbatim}
+ latex example
+ dvipdf example
+\end{verbatim}
+A more extensive test can be made by compiling the manual.
+
+To make a pdf file directly, with \program{pdflatex}, you use the commands
+\begin{verbatim}
+ pdflatex example
+ axohelp example
+ pdflatex example
+\end{verbatim}
+The \program{axohelp} run takes as input a file \file{example.ax1}
+produced by the first run of \program{pdflatex} and makes an output
+file \file{example.ax2}. The second run of \program{pdflatex} reads
+the \file{example.ax2} file and uses the result to place the axodraw
+objects in the \file{example.pdf} file.
+
+
+%--
+\subsubsection{Documentation}
+
+Put the documentation in a place where you can find it. If you
+installed the \file{axodraw2.sty} file in
+\file{/usr/local/texlive/texmf-local/tex/latex/axodraw2}, the
+standard place for the documentation would be
+\file{usr/local/texlive/texmf-local/doc/latex/axodraw2}.
+
+
+%=========================
+\section{Use}
+\label{sec:use}
+
+In this section we show how to use axodraw2, illustrated with an
+example.
+
+\subsection{Basic example}
+\label{sec:example}
+
+The principles of using axodraw2 are illustrated by the following
+complete \LaTeX{} document:
+\begin{verbatim}
+ \documentclass{article}
+ \usepackage{axodraw2}
+ \begin{document}
+ Example of Feynman graph using axodraw2 macros:
+ \begin{center}
+ \begin{axopicture}(200,110)
+ \SetColor{Red}
+ \Arc[arrow](100,50)(40,0,180)
+ \Text(100,100){$\alpha P_1 + \beta P_2 + k_\perp$}
+ \SetColor{Black}
+ \Arc[arrow](100,50)(40,180,360)
+ \Gluon(0,50)(60,50){5}{4}
+ \Vertex(60,50){2}
+ \Gluon(140,50)(200,50){5}{4}
+ \Vertex(140,50){2}
+ \end{axopicture}
+ \end{center}
+ \end{document}
+\end{verbatim}
+After compilation according to the instructions in Sec.\
+\ref{sec:doc.compile}, viewing the resulting file should show the
+following Feynman graph:
+\begin{center}
+ \begin{axopicture}(200,110)
+ \SetColor{Red}
+ \Arc[arrow](100,50)(40,0,180)
+ \Text(100,100){$\alpha P_1 + \beta P_2 + k_\perp$}
+ \SetColor{Black}

+ \Gluon(140,50)(200,50){5}{4}
+ \Vertex(140,50){2}
+ \end{axopicture}
+\end{center}
+See Sec.\ \ref{sec:examples} for more examples
+
+\emph{Important note about visibility of graphics objects:} If you
+view this document on a computer monitor, Feynman graphs drawn with
+narrow lines may not fully match what was intended. This is because
+of the way graphics viewers interact with the limited resolution of
+computer monitors. To see the example graphs properly, you may need to
+use a large enough magnification, or to use an actual print out.
+
+\emph{Note about sending a document to others}: If for example, you
+submit an article to arXiv.org, it is likely that their automated
+system for processing the file will not run \program{axohelp}. So together with
+the tex file, you one should also submit the \file{.ax2} file.
+

+\subsection{Document preparation}
+\label{sec:doc.prep}
+
+The general rules for preparation of a document are:
+\begin{itemize}
+
+\item Insert the following
+ \begin{verbatim}
+ \usepackage{axodraw2}
+ \end{verbatim}
+ in the preamble of the \file{.tex} file.
+ There are some options and commands that can be used to change axodraw2's
+ behavior from its default. See Secs.\ \ref{sec:invoke} and
+ \ref{sec:settings} for details.
+
+\item Where you want to insert axodraw2 objects, put them inside an
+ axopicture environment, specified in Sec.\ \ref{sec:env},
+ \begin{verbatim}
+ \begin{axopicture}(x,y)
+ ...
+ \end{axopicture}
+ \end{verbatim}
+ Here \texttt{x} and \texttt{y} denote the desired size of the box
+ that is to be inserted in the document and that contains the graph.
+ An optional offset can be specified (as with \LaTeX's
+ \texttt{picture} environment). By default the units are
+ $\unit[1]{pt} = \unit[1/72.27]{in} = \unit[0.3515]{mm}$.
+
+\end{itemize}
+Full details of all these components are in Sec.\
+\ref{sec:reference}.
+
+The design of graphs can be done manually, and this can be greatly
+facilitated with the new \verb:\AxoGrid: command. A convenient way of
+constructing diagrams is to use the graphical program
+JaxoDraw~\cite{jaxodraw1,jaxodraw2}, which is what most people
+do. This program can export axodraw code. It also uses axodraw as one
+way of making postscript and pdf files. The original version of
+axodraw was used by JaxoDraw until version 1.3. In version 2 of
+JaxoDraw, a specially adapted version of \file{axodraw.sty} is used,
+named \file{axodraw4j.sty}. The output from version 2 of
+JaxoDraw is compatible with axodraw2.
+
+
+%-----------------------
+\subsection{Document compilation}
+\label{sec:doc.compile}
+
+\subsubsection{To make a postscript file}
+\label{sec:doc.compile.ps}
+
+When a postscript file is needed, you just make the postscript file as
+usual. E.g., when the source file is \file{example.tex}, you run
+the following commands:
+\begin{verbatim}
+ latex example
+ dvips example -o
+\end{verbatim}
+which results in a postscript file \file{example.ps}. Of course, if
+there are cross references to be resolved, you may need multiple runs
+of \program{latex}, as usual. When needed, use of \program{bibtex},
+\program{makeindex}, and other similar programs is also as usual.
+Instead of \program{latex}, one may also use the \program{dvilualatex}
+program, which behaves like \program{latex} except for providing some
+extra capabilities that are sometimes useful.
+
+Internally, axodraw uses \TeX's \verb+\special+ mechanism to put
+specifications of postscript code into the \file{.dvi} file, and
+\program{dvips} puts this code in the postscript file. This postscript
+code performs the geometrical calculations needed to specific
+axodraw's objects, and then draws them when the file is displayed or
+printed.
+
+\emph{Important note about configuration of \program{dvips}:} You may
+possibly find that when you run \program{dvips} that it spends a lot of
+time running \program{mktexpk} to make bitmapped fonts, or that the
+postscript
+file contains bitmapped type-3 fonts. This is \emph{not} the default
+situation in typical current installations. But if you do find this
+situation, which is highly undesirable in most circumstances, you
+should arrange for \program{dvips} to use type 1 fonts. This can be
+done either by appropriately configuring your \TeX{} installation, for
+which you will have to locate instructions, or by giving
+\program{dvips} its \texttt{-V0} option:
+\begin{verbatim}
+ dvips -V0 example -o
+\end{verbatim}
+Once you do this, you should see, from \program{dvips}'s output,
+symptoms of its use of type 1 fonts. \emph{Let us re-emphasize that
+ you do not have to be concerned with this issue, under
+ normal circumstances. But since things were different within our
+ memory, we give some suggestions as to what to do in what are
+ currently abnormal circumstances.}
+
+\subsubsection{To make a pdf file via \program{latex}}
+
+There are multiple methods of making pdf files for a latex document;
+we will not give all the advantages and disadvantages here.
+
+One way is to convert the postscript file, e.g., by
+\begin{verbatim}
+ ps2pdf example.ps
+\end{verbatim}
+You can also produce a pdf file from the dvi file produced by
+\program{latex} by the \program{dvipdf} command, e.g,.
+\begin{verbatim}
+ dvipdf example
+\end{verbatim}
+\emph{Important note:} The program here is \program{dvipdf} and
+\emph{not} the similarly named \program{dvipdfm} or \program{dvipdfmx},
+which are incompatible with axodraw. The reason why \program{dvipdf}
+works is that it internally makes a postscript file and then converts
+it to pdf.
+
+
+\subsubsection{To make a pdf file by \program{pdflatex},
+ \program{lualatex}, or \program{xelatex}}
+
+A common and standard way to make a pdf file is the \program{pdflatex}
+program, which makes pdf directly. It has certain advantages, among
+which are the possibility of importing a wide variety of graphics file
+formats. (In contrast, the \program{latex} program only handles
+encapsulated postscript.)
+
+However, to use axodraw2 with \program{pdflatex}, you need an
+auxiliary program, \program{axohelp}, as in
+\begin{verbatim}
+ pdflatex example
+ axohelp example
+ pdflatex example
+\end{verbatim}
+What happens is that during a run of \program{pdflatex}, axodraw2
+writes a file \file{example.ax1} containing specifications of its
+graphical objects. Then running \program{axohelp} reads the
+\file{example.ax1} file, computes the necessary pdf code to draw the
+objects, and writes the results to \file{example.ax2}. The next run
+of \program{pdflatex} reads \file{example.ax2} and uses it to put the
+appropriate code in the output pdf file.
+
+The reason for the extra program is that axodraw needs many
+geometrical calculations to place and draw its graphical objects.
+\LaTeX{} itself does not provide anything convenient and efficient for
+these calculations, while the PDF language does not offer sufficient
+computational facilities, unlike the postscript language.
+
+If you modify a document, and recompile with \program{pdflatex}, you
+will only need to rerun \program{axohelp} if the modifications
+involve axodraw objects. Axodraw2 will output an appropriate message
+when a rerun of \program{axohelp} is needed.
+
+If you wish to use \program{lualatex} or \program{xelatex}, instead of
+\program{pdflatex}, then you can simply run the program
+\program{lualatex} or \program{xelatex} instead of
+\program{pdflatex}. These are equally compatible with axodraw2.
+
+
+
+
+%-----------------------
+\subsection{Automation of document compilation}
+\label{sec:doc.auto.compile}
+
+It can be useful to automate the multiple steps for compiling a
+\LaTeX{} document. One of us has provided a program \program{latexmk}
+to do this --- see \url{http://www.ctan.org/pkg/latexmk/}. Here we
+show how to configure
+\program{latexmk} to run \program{axohelp} as needed when a document is
+compiled via the \program{pdflatex} route.
+
+All you need to do is to put the following lines in one of
+\program{latexmk}'s initialization files (as specified in its
+documentation):
+\begin{verbatim}
+ add_cus_dep( "ax1", "ax2", 0, "axohelp" );
+ sub axohelp { return system "axohelp \"$_[0]\""; }
+ $clean_ext .= " %R.ax1 %R.ax2";
+\end{verbatim}
+The first two lines specify that \program{latexmk} is to make
+\file{.ax2} files from \file{.ax1} files by the \program{axohelp}
+program, whenever necessary. (After that \program{latexmk}
+automatically also does any further runs of \program{pdflatex} that are
+necessary.) The last line is optional; it adds \file{.ax1} and
+\file{.ax2} files to the list of files that will be deleted when
+\program{latexmk} is requested to do a clean up of generated,
+recreatable files.
+
+\program{Latexmk} is installed by default by the currently common
+distributions of \TeX{} software, i.e., TeXLive and MiKTeX. It has as
+an additional requirement a properly installed Perl system. For the
+TeXLive distribution, this requirement is always met.
+
+With the above configuration, you need no change in how you invoke
+\program{latexmk} to compile a document, when it uses axodraw2. For
+producing postscript, you can simply use
+\begin{verbatim}
+ latexmk -ps example
+\end{verbatim}
+and for producing pdf via \program{pdflatex} you can use
+\begin{verbatim}
+ latexmk -pdf example
+\end{verbatim}
+Then \program{latexmk} takes care of whatever runs are needed of all
+the relevant programs, now including \program{axohelp}, as well
+whatever, possibly multiple, runs are needed for the usual programs
+(\program{latex}, \program{pdflatex}, \program{bibtex}, etc).
+

+
+%>>#] Introduction :
+%>>#[ The Commands :
+
+\section{Reference}
+\label{sec:reference}
+
+\subsection{Package invocation}
+\label{sec:invoke}
+
+To use the axodraw2 package in a \LaTeX{} document, you simply put
+\begin{verbatim}
+ \usepackage{axodraw2}
+\end{verbatim}
+in the preamble of the document, as normal.
+
+The \verb+\usepackage+ command takes optional arguments
+(comma-separated list of keywords) in square brackets, e.g.,
+\begin{verbatim}
+ \usepackage[v1compatible]{axodraw2}
+\end{verbatim}
+The options supported by axodraw2 are
+\begin{itemize}
+\item \texttt{v1compatible}: This makes axodraw2's operation more
+ compatible with v.\ 1. It allows the use of \verb+\B2Text+,
+ \verb+\G2Text+, and \verb+\C2Text+ as synonyms for the macros named
+ \verb+\BTwoText+, \verb+\GTwoText+, and \verb+\CTwoText+.
+ (You may wish also to use the \texttt{canvasScaleisUnitLength}
+ option, so that the scaling of the units in the \texttt{axopicture}
+ environment is the same as it was for the \texttt{picture}
+ environment used in v.\ 1.)
+\item \texttt{canvasScaleIs1pt}: Unit for canvas dimensions
+ in an \texttt{axopicture} environment is fixed at $\unit[1]{pt}$,
+\item \texttt{canvasScaleIsObjectScale}: Unit for canvas dimensions
+ in an \texttt{axopicture} environment are the same as those set for
+ axodraw objects (by the \verb+\SetScale+ macro). This is the
+ default setting, so the option need not be given.
+\item \texttt{canvasScaleIsUnitLength}: Unit for canvas dimensions
+ in an \texttt{axopicture} environment is the current value of
+ \verb+\unitlength+, exactly as for \LaTeX{}'s \texttt{picture}
+ environment. (Thus, this corresponds to the behavior of the
+ original axodraw v.\ 1, which simply used the \texttt{picture}
+ environment.)
+\item \texttt{PStextScalesIndependently}: Axodraw's text objects are
+ scaled by the factor set by the \verb+\SetTextScale+ command.
+\item \texttt{PStextScalesLikeGraphics}: Axodraw's text objects are
+ scaled by the factor set by same factor for its graphics objects,
+ i.e., the scale set by the \verb+\SetScale+ command.
+\end{itemize}
+(N.B. Default scaling factors are initialized to unity.)
+
+\emph{Note:} If you use \program{axodraw}'s commands for placing text
+and you use the standard \TeX{} Computer Modern fonts for the
+document, then when you compile your document you may get a lot of
+warning messages. These are about fonts not being available in
+certain sizes. To fix this problem invoke the package
+\program{fix-cm} in your document's preamble:
+\begin{verbatim}
+ \usepackage{fix-cm}
+\end{verbatim}
+It is also possible to use the package \program{lmodern} for the same
+purpose.
+
+
+\subsection{Environment(s)}
+\label{sec:env}
+
+The graphical and other objects made by axodraw2 are placed in an
+\texttt{axopicture} environment, which is invoked either as
+\begin{verbatim}
+ \begin{axopicture}(x,y)
+ ...
+ \end{axopicture}
+\end{verbatim}
+or
+\begin{verbatim}
+ \begin{axopicture}(x,y)(xoffset,yoffset)
+ ...
+ \end{axopicture}
+\end{verbatim}
+Here, the \dots{} denote sequences of axodraw2 commands, as documented
+in later sections, for drawing lines, etc. The \texttt{axopicture}
+environment is just like standard \LaTeX's \texttt{picture}
+environment,\footnote{In fact, the \texttt{axopicture} is changed from
+ the \texttt{picture} environment only by making some
+ axodraw-specific settings. So the \texttt{picture} environment that
+ was used in v.\ 1 may also be used with axodraw2; it merely has a
+ lack of automation on the setting of the canvas scale relative to
+ the object scale, and, in the future, other possible
+ initializations.}, except for doing some axodraw-specific
+initialization. It inserts a region of size \texttt{x} by \texttt{y}
+(with default units of $\unit[1]{pt} = \unit[1/72.27]{in} =
+\unit[0.3515]{mm}$). Here \texttt{x} and \texttt{y} are set to the
+numerical values you need.
+
+The positioning of axodraw objects is specified by giving $x$ and $y$
+coordinates, e.g., for the ends of lines. The origin of these
+coordinates is, by default, at the lower left corner of the box that
+\texttt{axopicture} inserts in your document. But sometimes,
+particularly after editing a graph, you will find this is not
+suitable. To avoid changing a lot of coordinate values to get correct
+placement, you can specify an offset by the optional arguments
+\texttt{(xoffset,yoffset)} to the \texttt{axopicture} environment,
+exactly as for \LaTeX's \texttt{picture} environment. The offset
+\texttt{(xoffset,yoffset)} denotes the position of the bottom left
+corner of the box inserted in your document relative to the coordinate
+system used for specifying object positions. Thus
+\begin{verbatim}
+ \begin{axopicture}(20,20)
+ \Line(0,0)(20,20)
+ \end{axopicture}
+\end{verbatim}
+and
+\begin{verbatim}
+ \begin{axopicture}(20,20)(-10,20)
+ \Line(-10,20)(10,40)
+ \end{axopicture}
+\end{verbatim}
+are exactly equivalent.
+
+Within an \texttt{axopicture} environment, all the commands that can
+be used inside an ordinary \texttt{picture} environment can also be
+used.
+
+We can think of the \texttt{axopicture} environment as defining a
+drawing canvas for axodraw's graphical and text objects.
+There are possibilities for manipulating (separately) the units used
+to specify the canvas and the objects. These can be useful for
+scaling a diagram or parts of it from an originally chosen design.
+See Secs.\ \ref{sec:units} and \ref{sec:settings} for details.
+
+
+\subsection{Graphics drawing commands}
+\label{sec:commands}
+
+In this section we present commands for drawing graphical objects,
+split up by category. Later, we will give: details of options to the
+line-drawing commands, explanations of some details about specifying
+gluons and about specifying arrow parameters, and then commands for
+textual objects and for adjusting settings (e.g., separation in a
+double line). Mostly, we present the commands by means of examples.
+Note that many of the arguments of the commands, notably arguments for
+$(x,y)$ coordinate values are delimited by parentheses and commas
+instead of the brace delimiters typically used in \LaTeX.
+
+It should also be noted that some commands provide different ways of
+performing the same task. For instance
+\begin{verbatim}
+ \BCirc(50,50){30}
+\end{verbatim}
+can also be represented by
+\begin{verbatim}
+ \CCirc(50,50){30}{Black}{White}
+\end{verbatim}
+when the current color is black. The presence of the BCirc command has been
+maintained both for backward compatibility, and because it represents
+a convenient short hand for a common situation. This also holds for similar
+commands involving boxes and triangles. For the new Polygon, FilledPolygon,
+RotatedBox and FilledRotatedBox commands we have selected a more minimal
+scheme.
+
+Similar remarks apply to the new feature of options for line drawing
+commands. Originally in v.\ 1, a line with an arrow would be coded as
+\begin{verbatim}
+ \ArrowLine(30,65)(60,25)
+\end{verbatim}
+It is now also possible to code using the general \verb+\Line+ macro,
+but with a keyword optional argument:
+\begin{verbatim}
+ \Line[arrow](30,65)(60,25)
+\end{verbatim}
+One advantage of the option method is a variety of other properties of
+an individual line may also be coded, as in
+\begin{verbatim}
+ \Line[arrow,arrowpos=1](30,65)(60,25)
+\end{verbatim}
+without the need to use separate global setting for the property, by
+the commands listed in Sec.\ \ref{sec:settings}, or by having a
+corresponding compulsory argument to the command.
+Which way to do things is a matter of user taste in particular
+situations.

+are first the position of the left bottom corner, then two values that tell
+the size of the divisions in the $x$ and $y$ direction. Next there are two
+values that specify how many divisions there should be in the $x$ and $y$
+direction. Then the color of the lines is given and finally the width of
+the lines. Note that if there are $(n_x,n_y)$ divisions there will be
+$n_x+1$ vertical lines and $n_y+1$ horizontal lines. The temporary use of
+this command can also be convenient when designing pictures manually.

+\label{sec:Arc}
+
+The commands in this section draw circular arcs in types corresponding

+these commands had names containing ``Arc'' and some ``CArc''. Some
+kinds had variant names containing ``Arcn'', whose the direction of
+drawing was clockwise instead of anticlockwise. In v.\ 2, we have
+tried to make the situation more consistent. First, all the old names
+have been retained, for backward compatibility. Second, a general
+purpose command \verb+\Arc+ has been introduced; in a single command,
+with the aid of optional arguments, it covers all the variants. See
+Secs.\ \ref{sec:options} and \ref{sec:arrows} for full details. The
+options can be used to specify the type of line (dashed, double,
+clockwise or anticlockwise), to specify the use of arrow, and its
+parameters, and to specify some of the line's parameters. The other
+commands in this section can also be given optional keyword arguments.

+\subsection{Text}
+\label{sec:text}
+
+%--#[ Implementation :
+
+Axodraw2 provides several commands for inserting text into diagrams.
+Some are for plain text, with a chosen placement and angle. Some
+allow placement of text inside boxes. There are two sets of commands.
+Some we call \TeX-text commands; these use the standard \LaTeX{} fonts
+as used in the rest of the document. The others we call
+postscript-text commands; these use a user-specified standard
+postscript font or, if the user wishes, the usual document font, at a
+user-chosen size.
+
+[\emph{Side issue:} In version 1 of axodraw, the difference between
+the classes of text command was caused by a serious implementation
+difficulty. With the then-available \LaTeX{} technology, certain
+graphic effects, could not be achieved within \LaTeX, at least not
+easily. So direct programming in postscript was resorted to, with the
+result that normal \LaTeX{} commands, including mathematics, were not
+available in the postscript-text commands. With the greatly improved
+methods now available, this has all changed, and the restrictions have
+gone. But since the commands and their basic behavior is already
+defined, we have retained the distinction between \TeX{}-text commands
+and postscript-text commands.]
+
+In the original version of Axodraw the commands for two lines inside a
+box were \verb:B2Text:, \verb:G2Text: and \verb:C2Text:. This causes
+some problems explained in Sec.\ \ref{sec:changes.wrt.1}. If you need to
+retain compatibility with v.\ 1 on this issue, e.g., with old files or
+old diagrams or for personal preference, you can use the
+\texttt{v1compatible} option when loading axodraw2 --- see Sec.\
+\ref{sec:invoke}.

+\verb+\Text+ writes text in the current \LaTeX{} font. The most
+general form is \verb+\Text(x,y)(theta)[pos]{text}+; but either or
+both of the theta and pos arguments (and their delimiters) can be omitted.
+It puts the text
+at focal point $(x,y)$, with a rotation by anticlockwise angle theta.
+The default angle is zero, and the default position is to
+center the text horizontally and vertically at the focal point. The
+position letters are any relevant combination of `l', `r', `t', and
+`b', as in the various
+\TeX/\LaTeX{} box commands to indicate left, right, top or bottom
+adjustment with respect to the focal point. No indication means

+The \verb:\rText: command gives a subset of the functionality of the
+\verb+\Text+ command. It is used for backward compatibility with
+Axodraw v.\ 1. The general form of the command is
+\verb:\rText(x,y)[mode][rotation]{text}:.
+Unlike the case with the \verb:\Text: command and typical standard
+\LaTeX{} commands, if the option letters are omitted, the square
+brackets must be retained.
+The coordinates $(x,y)$ are
+the focal point of the text. The third argument is \verb+l+,
+\verb+r+, or empty to indicate the justification of the text. The
+fourth argument is \verb+l+, \verb+r+, \verb+u+, or empty to indicate
+respectively whether the text is rotated left (anticlockwise) by 90
+degrees, is rotated right (clockwise) by 90 degrees, is upside-down,
+or is not rotated. The fifth argument is the text.
+This command is retained only for backward compatibility;
+for new diagrams it is probably better to use the the \verb:\Text:.

+The remaining text-drawing commands can use postscript fonts with an

+
+To set the font for later text-drawing commands in this class, the
+\verb:\SetPFont: command sets the `Postscript'
+font, e.g.,
+\begin{verbatim}
+ \SetPFont{Helvetica}{20}
+\end{verbatim}
+(This font is initialized by axodraw2 to Times-Roman at 10pt.)
+The font set in this way is used in the \verb:PText:, \verb:BText:,
+\verb:GText:, \verb:CText:, \verb:BTwoText:, \verb:GTwoText: and
+\verb:CTwoText: commands. The fonts that can be used are the 35 fonts
+that are made available by Adobe and that are normally available in
+all postscript interpreters, including printers. The fonts, together

+\subsection{Options}
+\label{sec:options}
+
+Almost all of axodraw2's line-drawing commands take optional
+arguments. The form here is familiar from many standard \LaTeX{}
+commands. The optional arguments are placed in square brackets after
+the command name, and are made of a comma-separated list of items of
+the form: \texttt{keyword} or \texttt{keyword=value}. The required
+arguments are placed afterwards.
+
+Optional arguments can be used to set particular characteristics of a
+line, e.g., whether it is dashed or has an arrow. They can also be
+used to set some of the line's parameters, to be used instead of
+default values. (The default values can be adjusted by commands
+listed in Sec.\ \ref{sec:settings}. Those commands are useful for
+adjusting parameters that apply to multiple lines, while the optional
+arguments are useful for setting parameters for individual lines.)
+
+The original axodraw only had different command names to determine
+whether lines were dashed, or had arrows, etc. The new version
+retains these commands,
+but now the basic commands
+(\verb:\Line:, \verb:\Arc:, \verb:\Gluon:, etc) can also be treated as
+generic commands, with the different varieties (dashed, double, and/or
+with an arrow) being set by options.
+
+The same set of options are available for all types of line. However,
+not all apply or are implemented for particular types of line. Thus,
+\texttt{clockwise} is irrelevant for a straight line, while
+\texttt{arrow} is not implemented for gluons, photons and zigzag
+lines. Warnings are given for unimplemented features, while
+inapplicable arguments are ignored.
+
+The full set of options.
+\begin{center}
+\begin{tabular}{ll}
+ color=\colorname & Set the line in this color. \\
+ colour=\colorname & Same as color=\colorname. \\
+ dash & Use a dashed line. \\
+ dsize=\num & Set the dash size (when a line is dashed). \\
+ dashsize=\num & Same as dsize=\num. \\
+ double & Use a double line. \\
+ sep=\num & Sets the separation for a double line. \\
+ linesep=\num & Same as sep=\num. \\
+ width=\num & Sets line width for this line only.\\[2mm]
+ clock & For arcs, makes the arc run clockwise. \\
+ clockwise & For arcs, makes the arc run clockwise. \\[2mm]
+ arrow & Use an arrow.\\
+ flip & If there is an arrow, its direction is flipped. \\
+
+ arrowpos=\num & The number should be between zero and one and\\
+ & indicates where along the line the arrow should be. \\
+ & 1 is at the end. 0.5 is halfway (the initial default).\\
+ arrowaspect=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowlength=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowheight=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowinset=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowscale=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowstroke=\num & See Sec.\ \ref{sec:arrows}. \\
+ arrowwidth=\num & See Sec.\ \ref{sec:arrows}. \\
+ inset=\num & Same as arrowinset.\\
+\end{tabular}
+\end{center}
+The options without an extra argument, e.g., \texttt{arrow}, are
+actually of a boolean type. That is, they can also be used with a
+suffix ``\texttt{=true}'' or ``\texttt{=false}'', e.g.,
+\texttt{arrow=true} or \texttt{arrow=false}.
+
+If an option is not provided, its default value is used. Defaults are
+no dashes, no double lines, anticlockwise arcs, no arrow and if an
+arrow is asked for, its position is halfway along the line. Other
+arrow settings are explained in Sec.\ \ref{sec:arrows}. There are
+also default values for dash size (3) and the separation of double
+lines (2).
+
+The full set of the generic line commands with their syntax is
+\begin{center}
+ \begin{tabular}{l}
+ \verb+\Line[options](x1,y1)(x2,y2)+ \\
+ \verb+\Arc[options](x,y)(r,theta1,theta2)+ \\
+ \verb+\Bezier[options](x1,y1)(x2,y2)(x3,y3)(x4,y4)+ \\
+ \verb+\Gluon[options](x1,y1)(x2,y2){amplitude}{windings}+ \\

+ \verb+\ZigZagArc[options](x,y)(r,theta1,theta2){amplitude}{windings}+ \\
+ \end{tabular}
+\end{center}
+The applicability of the options is as follows
+\begin{center}
+ \begin{tabular}{lcc}
+ & Arrow, etc & Clockwise \\

+The arrow options include those for setting the arrow dimensions.
+Options not indicated in the last table apply to all cases.

+% gray,grayscale=\num & Inside is in gray. Filled overwrites this. \\
+% rotation=\num & Only for centered boxes: rotation angle.
+%\end{tabular}
+%\end{center}
+%The options gray and filled imply blanked. Hence it is not needed to use
+%blanked when either of those options is used. The default values are that
+%none of these options are used.
+
+Some examples are:
+\begin{verbatim}
+ \Line[double,sep=1.5,dash,dsize=4](10,10)(70,30)
+ \Line[double,sep=1.5,arrow,arrowpos=0.6](10,10)(70,30)
+\end{verbatim}
+
+The options can also be used on the more explicit commands as extra
+options. Hence it is possible to use
+\begin{verbatim}
+ \DoubleLine[dash,dsize=4](10,10)(70,30){1.5}
+\end{verbatim}
+instead of the first line in the previous example.
+
+One may notice that some of the options are not accessible with the more
+explicit commands. For example, it is possible to put arrows on B\'ezier
+curves only by using the option `arrow' for the B\'ezier command.

+\subsection{Remarks about Gluons}
+\label{sec:gluon.remarks}
+
+There are 12 commands that concern gluons. This allows much freedom in
+developing one's own style. Gluons can be drawn as single solid lines, as
+double lines, as dashed lines and as dashed double lines.
+
+Gluons have an amplitude and a number of windings. By varying these
+quantities one may obtain completely different gluons as in:
+

+There are two ways of drawing a gluon circle. One is with the command

+(A complete list of commands for setting defaults is in
+Sec.\ \ref{sec:settings}.)
+These commands determine settings that will hold for all following
+commands, up to the end of whatever \LaTeX{} or \TeX{} grouping the
+default setting is given in. E.g., setting a default value inside an
+\texttt{axopicture} environment sets it until the end of the
+environment only. (Thus the settings obey the normal rules of
+\LaTeX{} for scoping.)
+
+The other way is to use one or more of these parameters as options in a
+command that uses an arrow. The general use of options is in Sec.\
+\ref{sec:options}. The options that are available are
+\begin{center}
+\begin{tabular}{ll}
+ arrow & initial default=false \\
+ arrowscale=\num & initial default=1 \\
+ arrowwidth=\num & initial default=0 \\
+ arrowlength=\num & initial default=0 \\
+ arrowpos=\num & initial default=0.5 \\
+ arrowinset=\num & initial default=0.2 \\
+ arrowstroke=\num & initial default=0 \\
+ arrowaspect=\num & initial default=1.25 \\
+ flip & initial default=false
+\end{tabular}
+\end{center}
+The arrow option tells the program to draw an arrow. Without it no
+arrow will be drawn. The flip option indicates that the direction of
+the arrow should be reversed from the `natural' direction.
+
+When
+neither the width nor the length are specified, but instead both are
+given as zero, they are computed from the line width (and the line
+separation when there is a double line). The formula is:
+\begin{eqnarray}
+ \mbox{Arrowwidth} & = &
+ 1.2 \times \left( \mbox{linewidth}
+ + 0.7 \times \mbox{separation}
+ + 1
+ \right)
+ \times \mbox{arrowscale},
+\\
+\label{arrowlength}
+ \mbox{Length} & = &
+ 2 \times \mbox{arrowwidth} \times \mbox{arrowaspect}.
+\end{eqnarray}
+%If however $\mbox{linewidth} + \frac{1}{4} \times \mbox{separation} <
+%0.5$ the formula for the arrow width becomes $\mbox{arrowwidth} = 2.5
+%\times \mbox{arrowscale}$.
+If, however, $1.2 \times(\mbox{linewidth}+0.7\times\mbox{separation}+1)$ is less
+than 2.5, the formula for the arrow width becomes
+$\mbox{arrowwidth}=2.5\times\mbox{arrowscale}$.
+
+If only one of the arrowwidth or the arrowlength parameters is zero,
+it is computed from the other non-zero parameter using formula
+(\ref{arrowlength}). When both are non-zero, those are the values that
+are used.
+
+The position of the arrowhead is a bit tricky. The arrowpos parameter is a
+fraction of the length of the line and indicates the position of the center
+of the arrowhead. This means that when arrowpos is one, the arrowhead
+sticks out beyond the end of the line by half the arrowlength. When for
+instance the line width is 0.5, the default length of the arrowhead
+defaults to 6.25. Hence if one would like to compensate for this one should
+make the line 3.125 points shorter. Usually 3 pt will be sufficient.
+
+Because of backward compatibility axodraw2 has many individual commands for
+lines with arrows. We present them here, together with some `options'
+varieties.\vspace{4mm}

+Computing the position of the arrow in a B\'ezier curve is a bit complicated.
+Let us recall the definition of a cubic B\'ezier curve:
+\begin{eqnarray}
+ x & = & x_0 (1-t)^3 + 3 x_1 t (1-t)^2 + 3 x_2 t^2 (1-t) + x_3 t^3
+ \nonumber \\
+ y & = & y_0 (1-t)^3 + 3 y_1 t (1-t)^2 + 3 y_2 t^2 (1-t) + y_3 t^3
+\end{eqnarray}
+Computing the length of the curve is done with the integral
+\begin{eqnarray}
+ L & = & \int_0^1 dt
+ \sqrt{ \left( \frac{dx}{dt} \right)^2 + \left( \frac{dy}{dt} \right )^2 },
+\end{eqnarray}
+which is an integral over the square root of a quartic polynomial. This we
+do with a 16 point Gaussian quadrature and it gives us more than enough
+accuracy\footnote{We need to compute the length of the B\'ezier curve also
+when we want to put a dash pattern on it. The exact dash size is determined
+such that an integer number of patterns fits in the line.}. Let us assume
+now that we want the arrow at 0.6 of the length. To find the exact fraction
+of the length involves finding the upper limit of the integral for which
+the length is $0.6 L$. This requires an iteration procedure till we have a
+reasonable accuracy for the position $(x,y)$. After that we have to calculate
+the derivative in this point as well.
+
+Because the B\'ezier curves are new commands in axodraw2 there is no need for
+backwards compatibility in the use of arrows. Hence all arrow commands are
+done by means of the options. Some examples are:

+\subsection{Units and scaling}
+\label{sec:units}
+
+When you have constructed a diagram, you may need to change its scale,
+to make it larger or smaller. Axodraw2 provides ways of doing this,
+for scaling diagrams without recoding all the individual coordinates.
+However the requirements for the nature of the scaling change between
+different cases. For example, suppose a diagram is designed for use in
+a journal article and you wish to use it in the slides for a seminar.
+Then you will want to enlarge both the geometric size of the diagram's
+objects and the text labels it contains. But if you wish to use a
+scaled diagram in another place in a journal article, you will wish to
+scale its lines etc, but will probably not wish to scale the text (to
+preserve its legibility).
+
+Axodraw2 therefore provides tools for the different situations, so we
+will now explain what to do. The commands to achieve this all appear
+in the list of parameter-setting commands in Sec.\ \ref{sec:settings}.
+
+
+\subsubsection{Scaling for slides}
+
+Suppose the original diagram is
+\begin{center}
+\begin{minipage}{10cm}
+\begin{verbatim}
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{verbatim}
+\end{minipage}
+\end{center}
+to give
+\begin{center}
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{center}
+Then you could double the scale of the diagram by
+\begin{center}
+\begin{minipage}{10cm}
+\begin{verbatim}
+ \SetScale{2}
+ \fontsize{24}{26}\selectfont
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{verbatim}
+\end{minipage}
+\end{center}
+to get
+\begin{center}
+ \SetScale{2}
+ \fontsize{24}{26}\selectfont
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{center}
+We have changed the size of the document font, as would be appropriate
+for a make slides for a presentation; this we did by the
+\verb+\fontsize+ command. The arc and the space inserted
+in the document for the diagram have scaled up. The label inserted by
+the \verb:\Text: command has changed to match the document font. The
+postscript text in the \verb:\CText: was specified to be at
+$\unit[12]{pt}$, but is now scaled up also.
+
+The above behavior is what axodraw2 does by default, and is what v.\ 1
+did.
+
+
+\subsubsection{Scaling within article}
+
+If you wanted to make an enlarged figure in a journal article, you
+would not change the document font. But the obvious modification to
+the previous example is
+\begin{center}
+\begin{minipage}{10cm}
+\begin{verbatim}
+ \SetScale{2}
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{verbatim}
+\end{minipage}
+\end{center}
+which gives
+\begin{center}
+ \SetScale{2}
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{center}
+The label $\alpha P_1$ is now not enlarged, since it copies the
+behavior of the document font. But the postscript text is enlarged,
+which is probably undesirable. If you were scaling down the diagram
+instead of scaling it up, the situation would be worse, because the
+postscript font would be difficult to read.
+
+So in this situation, of scaling the diagram while keeping the
+document font intact, you probably also want to leave unchanged the
+size of the postscript font. You can achieve this by the
+\verb:\PSTextScalesLikeGraphicsfalse: command:
+\begin{center}
+\begin{minipage}{10cm}
+\begin{verbatim}
+ \SetScale{2}
+ \PSTextScalesLikeGraphicsfalse
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{verbatim}
+\end{minipage}
+\end{center}
+\begin{center}
+ \SetScale{2}
+ \PSTextScalesLikeGraphicsfalse
+ \SetPFont{Helvetica-Oblique}{12}
+ Document text. Then diagram:
+ \begin{axopicture}(60,43)
+ \Arc[arrow](30,0)(30,0,180)
+ \Text(30,33)[b]{$\alpha P_1$}
+ \CText(30,10){Red}{Yellow}{Arc}
+ \end{axopicture}
+\end{center}
+
+To achieve this on a document-wide basis, which is probably what you
+want, you can use the \texttt{PStextScalesIndependently} option when you
+load axodraw2 --- see Sec.\ \ref{sec:invoke}.
+
+Nevertheless, if you turn off the default scaling of postscript text,
+%you may still want to scale text. To do this you can use the
+you may still want to scale text. For this you can use the
+\verb:\SetTextScale: command, as in \verb:\SetTextScale{1.2}:. This
+only has an effect when you have turned off the scaling of postscript
+text with graphics objects; but then it applies to \TeX{} text
+inserted by axodraw2's \verb:\Text: and \verb:\rText: commands, as
+well text inserted by axodraw2's ``postscript-text'' commands.
+
+If you are confused by the above, we recommend experimentation to
+understand how to achieve the effects that you specifically need. We
+could have made the set of commands and options simpler, but only at
+the expense of not being able to meet the demands of the different
+plausible situations that we could imagine and have to deal with
+ourselves.
+
+\subsubsection{Canvas and object scales}
+
+When you use \verb:\SetScale: outside an \verb:axopicture:
+environment, as above, the scaling applies to both the axodraw2
+objects and the space inserted for the \texttt{axopicture} environment
+in the document, as is natural. But you may find you need to scale a
+subset of objects inside the diagram, e.g.,
+\begin{center}
+ \begin{minipage}{10cm}
+ \verb:\begin{axopicture}:(\dots)\\
+ \hspace*{1cm} (First block)\\
+ \verb:\SetScale{0.5}:\\
+ \hspace*{1cm} (Second block)\\
+ \verb:\end{axopicture}:
+ \end{minipage}
+\end{center}
+In this case, the units for specifying the objects in the second block
+are different from those for specifying the \verb:axopicture:
+environment's size (as well as the first block of objects). We thus
+distinguish object units from canvas units, where ``canvas'' refers to
+the \verb:axopicture: environment as a whole.
+
+Another complication is that the \LaTeX{} \verb+picture+ environment
+has is own \verb:\unitlength: parameter. In v.\ 1 of axodraw, the
+canvas scale was determined by \LaTeX's \verb:\unitlength:. But there
+was an independent unit for the object scale; this was the one
+determined by axodraw's \verb:\SetScale: command. Also, not all
+objects used the object scale. The situation therefore got quite
+confusing. In v.\ 1, if, as is often natural, you wished to scale the
+canvas as well as the objects, you would have needed to set \LaTeX's
+\verb:\unitlength: parameter as well as using axodraw's
+\verb:\SetScale: command.
+
+So now we have arranged things so that the canvas and object scales
+are tied by default, provided that you use axodraw2's \verb:\SetScale:
+command, and that axodraw diagrams are inside \verb+axopicture+
+environments (in contrast to the \verb+picture+ environment used in
+the original axodraw).
+However, it may be necessary to keep backward compatibility in some
+cases, and we weren't certain that the new behavior is exactly what is
+always desired. So in axodraw2, we have provided three choices, given
+by the \texttt{canvasScaleIs1pt}, \texttt{canvasScaleIsObjectScale},
+and \texttt{canvasScaleIsUnitLength} options when loading axodraw2 ---
+see Sec.\ \ref{sec:invoke}. Naturally,
+\texttt{canvasScaleIsObjectScale} is the default. If you wish to
+change the setting mid-document, there are corresponding commands ---
+Sec.\ \ref{sec:settings}.
+
+
+
+\subsection{Settings}
+\label{sec:settings}
+
+Axodraw2 has a number of parameters that can be set by the user. The
+parameters include defaults for line types, dimensions, etc. The
+parameters can be set either inside the axopicture environment or
+outside. If they are set outside they modify the default value for
+subsequent pictures. If set inside they only affect the current
+picture. (In general, the parameters obey the usual rules for the
+scope of \LaTeX{} variables.) In many cases, the parameters provide
+default values for a command to draw an object and can be overridden
+for a single object by using an optional parameter in invoking the
+command for the object.
+
+The unit for lengths is the current object scale, as set by the
+\verb+\SetScale+ command.

+\subsection{Colors}
+\label{sec:colors}
+
+\TeX{} and \LaTeX{} by themselves do not provide any means to set
+colors in a document. Instead, one must use a suitable package to
+achieve the effect; the current standard one is \file{color.sty}.
+Such a package performs its work by passing graphics commands to the
+viewable output file. Since axodraw also works in a similar fashion,
+there is a potentiality for conflicts.
+
+Axodraw version 1, released in 1994, used the package
+\file{colordvi.sty} for applying color to normal textual material,
+and its own separate methods for applying color to its graphical
+objects. They both defined the same convenient set of named colors
+that could be used, but they had to be set separately for text and
+graphics\footnote{The named colors corresponded to ones defined by the
+ \program{dvips} program.}. The \file{colordvi.sty} package also had
+an important disadvantage that its color settings did not respect
+\TeX{} grouping and \LaTeX{} environments, so that a color setting
+made for text in an environment continued to apply after the end of
+the environment.
+
+Since then, the available tools, notably in the powerful
+\file{color.sty}, have greatly improved. But this has introduced
+both real and potential incompatibilities with the older methods.
+Note that \file{color.sty} is currently the most standard way for
+implementing color, and is a required part of \LaTeX{} distributions,
+as part of the graphics bundle.
+
+In the new version of axodraw, we have arranged to have compatibility
+with \file{color.sty}, while allowing as much backward compatibility
+as we could with the user interface from v.\ 1. We fully rely on
+\file{color.sty} for setting color\footnote{Except for certain hard
+ wired settings in double lines and stroked arrows.}. But to keep
+the best of the old methods, we have defined all the named colors that
+were defined in the old version, together with a few extra ones. We
+have also defined color-setting commands in the style of
+\file{colordvi.sty}, but they now apply uniformly to both text and
+axodraw graphical objects, and they respect \TeX{} and \LaTeX{}
+grouping and environments.
+
+This results in some changes in behavior in certain situations. We
+think the new behavior is more natural from the user's point of view;
+but it is a change.
+
+There are two classes of graphics-drawing command in axodraw. One
+class has no explicit color argument, and uses the currently set
+color; the line-drawing commands are typical of these. Other commands
+have explicit color arguments, and these arguments are named colors.
+The named colors are a union of those axodraw defines, with those
+defined by \file{color.sty} together with any further ones defined
+by the user.
+
+\subsubsection{How to use colors}
+
+Axodraw works with named colors --- see Sec.\ \ref{sec:defined.colors}
+--- which are a standard set of 68 originally defined by the \program{dvips}
+program and the \file{colordvi.sty}, plus 5 extra colors defined in
+axodraw2. (In addition there are several named colors that are
+normally defined by default by \file{color.sty}, and that can also
+be used.)
+
+To use them we have several possibilities to specify colors. Which to
+use is mostly a matter of user preference or convenience.
+\begin{itemize}
+
+\item The axodraw command \verb+\SetColor{colorname}+: sets the color
+ to be the named color for everything until the end of the current
+ environment (or \TeX{} group, as relevant.) The initial default
+ color is Black, of course. An example:
+ \begin{center}
+ \begin{minipage}{4cm}
+ \SetColor{Red}
+ Now red is used:\\
+ \begin{axopicture}(0,40)
+ \Line(0,10)(40,30)
+ \end{axopicture}
+ \end{minipage}
+ \begin{minipage}{7cm}
+ \label{SetColor}
+ \begin{verbatim}
+ \SetColor{Red}
+ Now red is used:\\
+ \begin{axopicture}(0,40)
+ \Line(0,10)(40,30)
+ \end{axopicture}
+ \end{verbatim}
+ \end{minipage}
+ \end{center}
+
+\item Completely equivalently, one can use the command
+ \verb+\color{colorname}+ defined by the standard \file{color.sty}
+ package, with any of its options, e.g., \verb+\color{Red}+ or
+ \verb+\color[rgb]{1,0,0}+. In fact \verb+\SetColor+ is now a
+ synonym for \verb+\color+, retained for backward compatibility.
+
+\item The named colors defined by axodraw2 are listed in Sec.\
+ \ref{sec:defined.colors}. Extra ones can be defined by axodraw2's
+ \verb+\newcolor+ command.
+
+\item For each of the named colors defined by axodraw2 (and others
+ defined by the use of the \verb+\newcolor+ command), there is a
+ macro whose name is ``text'' followed by the color name, e.g.,
+ \verb+\textMagenta+. This behaves just like the corresponding call
+ to \verb+\SetColor+ or \verb+\color+. Thus we have
+ \begin{center}
+ \begin{minipage}{4cm}
+ \textMagenta
+ Now magenta is used: \hfill \\
+ \begin{axopicture}(0,40)
+ \Line(0,10)(40,30)
+ \end{axopicture}
+ \end{minipage}
+ \begin{minipage}{7cm}
+ \label{textName}
+ \begin{verbatim}
+ \textMagenta
+ Now magenta is used:\\
+ \begin{axopicture}(0,40)
+ \Line(0,10)(40,30)
+ \end{axopicture}
+ \end{verbatim}
+ \end{minipage}
+ \end{center}
+ These macros correspond to macros defined by the venerable
+ \file{colordvi.sty} package, but now have what is normally an advantage
+ that their scope is delimited by the enclosing environment.
+ \begin{center}
+ \begin{minipage}{5cm}
+ Normal text, then
+ \begin{center}
+ \Large \bf \color{Blue}
+ Large, bold blue\\
+ \begin{axopicture}(40,20)
+ \Gluon(0,10)(40,10){4}{4}
+ \end{axopicture}\\
+ \end{center}
+ And normal text afterward.
+ \end{minipage}
+ \begin{minipage}{7.7cm}
+ \label{scope}
+ \begin{verbatim}
+ Normal text, then
+ \begin{center}
+ \Large \bf \color{Blue}
+ Large, bold blue
+ \begin{axopicture}(40,20)
+ \Gluon(0,10)(40,10){4}{4}
+ \end{axopicture}\\
+ \end{center}
+ And normal text afterward.
+ \end{verbatim}
+ \end{minipage}
+ \end{center}
+
+\item A delimited section of text can be set in a color by using a
+ macro named by the color (e.g., $\verb+\Red+$):
+ \begin{center}
+ \begin{minipage}{6cm}
+ In the middle of black text,
+ \textcolor{Red}{red text and
+ \begin{axopicture}(30,10)
+ \Gluon(0,5)(30,5){3}{4}
+ \end{axopicture}\
+ gluon%
+ }.
+ Then continue \dots
+ \end{minipage}
+ \begin{minipage}{7.3cm}
+ \label{Red}
+ \begin{verbatim}
+ In the middle of black text,
+ \Red{red text and
+ \begin{axopicture}(30,10)
+ \Gluon(0,5)(30,5){3}{4}
+ \end{axopicture}\
+ gluon%
+ }.
+ Then continue \dots
+ \end{verbatim}
+ \end{minipage}
+ \end{center}
+ These macros correspond to macros defined by the \file{colordvi.sty}
+ package, but they now apply to axodraw objects as well.
+
+\item The same effect, for named colors, can be achieved by
+ \file{color.sty}'s \verb+\textcolor+ macro. Thus
+ \verb+\textcolor{Red}{...}+ is equivalent to \verb+\Red{...}+.
+
+\end{itemize}
+
+It is also possible to define new named colors, in the CMYK
+system. This means that each color is defined by four numbers. New
+colors can be introduced with the \verb:\newcolor{#1}{#2}: command as
+in \verb:\newcolor{LightRed}{0 0.75 0.7 0}:. This use of this command
+defines a named color for use in axodraw, with corresponding macros
+\verb:\LightRed: and \verb:\textLightRed{#1}:, and also makes the name
+known to \file{color.sty}. (Use of \file{color.sty}'s
+\verb:\definecolor: macro is not supported here: it will affect only
+normal \LaTeX{} text, but not axodraw objects, and it will fail to
+define the extra macros.)
+
+We define the CMYK values for the named colors in the
+\file{axodraw2.sty} file. These override the definitions provided
+by \file{color.sty} (in its file dvipsnam.def), which are the same
+(at least currently).
+
+There can be differences in how colors render on different devices.
+In principle, there should be compensations made by the driver to
+compensate for individual device properties. Our experience is however
+that such compensations are not always implemented well enough. Most
+notorious are differences between the shades of green on the screen,
+on projectors, and on output from a printer. These colors are usually
+much too light on a projector and one way to correct this is to
+redefine those colors when the output is prepared for a projector,
+e.g., by use of axodraw's \verb:\newcolor{#1}{#2}: macro. An example
+is illustrated by
+\begin{center}
+ \color{green}
+ \begin{axopicture}(100,20)
+ \Text(25,15){color.sty's green}
+ \Line[width=2](0,0)(50,0)
+ \end{axopicture}
+%
+ \color{Green}
+ \begin{axopicture}(100,20)
+ \Text(25,15){axodraw's Green}
+ \Line[width=2](0,0)(50,0)
+ \end{axopicture}
+\end{center}
+coded by
+\begin{verbatim}
+ \color{green}
+ \begin{axopicture}(100,20)
+ \Text(25,15){color.sty's green}
+ \Line[width=2](0,0)(50,0)
+ \end{axopicture}
+%
+ \color{Green}
+ \begin{axopicture}(100,20)
+ \Text(25,15){axodraw's Green}
+ \Line[width=2](0,0)(50,0)
+ \end{axopicture}
+\end{verbatim}
+On a typical screen or projector, we find that the two greens are
+quite distinct, the ``green'' being much lighter than the
+``Green''\footnote{The ``green'' is defined in the RGB scheme from the
+ values $(0,1,0)$, while ``Green'' is defined in the CMYK scheme from
+ the values $(1,0,1,0)$.}. But on the paper output from our
+printers, they give close results.

+\subsection{A Feynman diagram}
+
+When computing the singlet part of structure functions in polarized Deep
+Inelastic Scattering one approach is to use spin two currents to determine
+all anomalous dimensions. At the three loop level this can give diagrams
+like the following:
+\begin{center}
+\begin{axopicture}{(200,140)(0,0)}

+\section{The \program{axohelp} program: Information for developers}
+\label{sec:axohelp.devel}
+
+This appendix provides some details on how the \program{axohelp} program works.
+Most of the information is only relevant to people who wish to modify
+or extend axodraw2 and therefore may need to modify \program{axohelp} as well.
+
+The reason for \program{axohelp}'s existence is that axodraw needs to perform
+substantial geometric calculations. When axodraw is used with
+pdflatex to produce pdf output directly, suitable calculational
+facilities are not available, neither within the PDF language nor
+within \LaTeX{} itself. Therefore when axodraw is used under
+pdflatex, we use our program \program{axohelp} to perform the calculations.
+
+The mode of operation is as follows. Let us assume that the
+\file{.tex} file being compiled by the \program{pdflatex} program is
+called \file{paper.tex}. When one issues the command
+\begin{verbatim}
+ pdflatex paper
+\end{verbatim}
+the reaction of the system is of course to translate all \TeX{}
+related objects into a PDF file. Most (but not all) axodraw objects
+need non-trivial calculations and hence their specifications are
+placed inside a file called \file{paper.ax1}. At the end of the
+processing \program{pdflatex} will place a message on the screen that
+mentions that the user should run the command
+\begin{verbatim}
+ axohelp paper
+\end{verbatim}
+for the processing of this graphical information. In principle it is
+possible to arrange for \program{axohelp} to be invoked automatically from
+within pdflatex. But for this to be done, the running of general
+external commands from pdflatex would have to be enabled. That is a
+security risk, and is therefore normally disabled by default for
+pdflatex.
+
+When run, \program{axohelp} reads the file \file{paper.ax1}, processes the
+contents, and produces a file \file{paper.ax2}. For each axodraw
+object, it contains both the code to be placed in the pdf file, and a
+copy of the corresponding specification that was in \file{paper.ax1}.
+
+When pdflatex is run again, it sees that the file \file{paper.ax2} is
+present and reads it in to give essentially an array of objects, one
+for each processed axodraw object. Then during the processing of the
+document, whenever axodraw runs into an axodraw object in need of
+external calculation, it determines whether an exactly corresponding
+specification was present in the file \file{paper.ax2}. If not, it
+means that the graphical information in the file \file{paper.tex} has
+changed since the last run of \program{axohelp} and the graphics information is
+invalidated. In that case, at the end of the program the message to
+run \program{axohelp} will be printed again. But if instead there is an exact
+match between an axodraw object in the current \file{paper.tex} and
+its specification in \file{paper.ax2}, then the corresponding pdf code
+will be placed in the PDF file. If all axodraw commands have a proper
+match in the \file{paper.ax2} file, there will be no message in the
+paper.log file and on the screen about rerunning \program{axohelp}; then the PDF
+file should contain the correct information for drawing the axodraw
+objects (at least if there are no \TeX{} errors).
+
+In a sense the situation with \program{axohelp} is no different from the use of
+makeindex when one prepares a document that contains an index. In that
+case one also has to run \LaTeX{} once to prepare a file for the
+makeindex program, then run this program which prepares another file
+and finally run \LaTeX{} again. Note that if you submit a paper to
+arXiv.org, it is likely that their automated system for processing the
+file will not run \program{axohelp}. So together with \file{paper.tex}, you one
+should also submit the \file{.ax2} file.
+
+The complete source of the \program{axohelp} program can be found in the file
+\file{axohelp.c}. This file contains a bit less than 4000 lines of C
+code but should translate without problems with any C compiler --- see
+Sec.\ \ref{sec:axohelp} for an appropriate command line on typical
+Unix-like systems.
+
+The \program{axohelp} program functions as follows:
+\begin{enumerate}
+\item The \file{.ax1} file is located, space is allocated for it and
+ the complete file is read and closed again.
+\item The input is analysed and split in individual object
+ specifications, of which a list is made.
+\item The list of object specifications is processed one by
+ one. Before the processing of each object specification, the system
+ is brought to a default state to avoid that there is a memory of the
+ previous object.
+\item In the \file{.ax2} file, for each object is written both the
+ corresponding pdf code and a copy of the specification of the object
+ as was earlier read from the \file{.ax1} file. Before the output
+ for an object is written to the \file{.ax2} file it is optimized a
+ bit to avoid superfluous spaces and linefeeds.
+\end{enumerate}
+
+Processing an object from the input involves finding the proper routine for
+it and testing that the number of parameters is correct. Some objects have
+a special input (like the Curve, DashCurve, Polygon and FilledPolygon
+commands). All relevant information is stored in an array of double
+precision numbers. Then some generic action is taken (like setting the
+linewidth and the color) and the right routine is
+called. The output is written to an array of fixed (rather large) length.
+Finally the array is optimized and written to file.
+
+A user who would like to extend the system with new objects should
+take the above structure into account. There is an array that gives
+the correspondence between axodraw object names and the corresponding
+routine in \program{axohelp}. For each object, this array also gives the number
+of parameters and whether the stroking or non-stroking color space
+should be used.
+
+Naturally, when adding new kinds of object, it is necessary to add new
+items to the just-mentioned array, and to add a corresponding
+subroutine. One should also try to do all the writing of PDF code by
+means of some routines like the ones sitting in the file in the
+section named ``PDF utilities''. This is important from the viewpoint
+of future action. When new graphical languages will be introduced and
+it will be needed to modify axodraw2 such that it can produce code for
+those languages, it should be much easier if code in the supporting
+\program{axohelp} program needs to be changed in as few places as possible.
+They form a set of graphics primitives used by other subroutines.
+Some of these subroutines in the ``PDF utilities'' section of
+\file{axohelp.c} have names similar to operators in the postscript
+language that perform the same function.

+%
+% Code necessities:
+%
+% 1. \ignorespaces at end of commands that draw things. Often it won't
+% matter, but occasionally a command in a picture environment
+% will set material and a following uncommented end-of-line in
+% the user's code will shift the insertion point.
+% 2. Use end-of-line comments whereever TeX might use the end-of-line as
+% a space to be typeset.
+%
+% Conventions
+%
+% 1. Any font and color changes that are supposed to be local should
+% be made local, either by explicit TeX grouping or by being
+% inside commands (e.g., box-making commands) that enforce groups.
+% Braces work, but \begingroup and \endgroup are easier to see in
+% multiline groups.
+% 2. Scaling:
+% \unitlength is the unit for the canvas (as in picture environment).
+% \axoscale is for the unit for coordinates, widths, etc
+% \axotextscale is for all text objects, BUT only when
+% PSText is NOT set to scale as graphics objects
+% When PSText is set to scale as graphics objects, PSText
+% scales by \axoscale, but TeX-text has unit scaling.
+% Given a specification of a position (x,y) as in a call to \Line,
+% the position of the point relative to the origin is
+% x_act = (x + \axoxo ) \axoscale pt + \axoxoffset \unitlength
+% y_act = (y + \axoyo ) \axoscale pt + \axoyoffset \unitlength
+% Widths and the like for lines are in units of \axoscale pt
+%
+% #[ About folds : (this line starts with one % and two tabs)
+%
+% The internals of the file have been organized in folds.
+% These are defined as a range of lines if which the first and last
+% lines have a special format. Each starts with any three characters
+% (may include tabs), then #[ for the start line and #] for the closing
+% line, then both lines need identical name fields, closed by a colon.
+% After the colon can be anything. When a fold is closed one should see
+% only the first line but with the #[ replaced by ## as in
+% ## About folds : (this line starts with one % and two tabs)
+% Folds can be nested.
+% This fold concept comes originally from the occam compiler for the
+% transputer in the second half of the 1980's although there it was
+% implemented differently. It was taken over by the STedi editor in its
+% current form. The sources of this editor are available from the form
+% home site: http://www.nikhef.nl/~form
+% Some people have managed to emulate these folds in editors like emacs
+% and vim.

+% Settings for pdf v. dvi/ps output:
+% We need to be able to run under latex, pdflatex, lualatex, and
+% xelatex, and use (if possible) \pdfoutput and \pdfliteral
+%
+% latex: Initially \pdfoutput is 0, and \pdfliteral is defined but
+% not usable.
+% pdflatex: Initially \pdfoutput is 1, and \pdfliteral is defined and
+% usable.
+% lualatex: same as pdflatex in versions up to 0.80
+% But in versions from 0.85, pdfouput and pdfliteral aren't
+% defined; instead \outputmode, \pdfextension literal{...}
+% are available instead.
+% xelatex: Both \pdfoutput and \pdfliteral are undefined
+% but special{pdf:literal ...} gives same effect as
+% \pdfliteral would, and we can assume pdf mode always.
+% When \pdfoutput is defined, the user can change its value to change
+% the type of output. This must be done before the first page is
+% created. But various packages (including graphics and ifpdf, as
+% well as axodraw) take actions when the package is loaded that depend
+% on current state of \pdfoutput (or its equivalent). So it is
+% reasonable to require that \pdfoutput be set only before packages
+% are loaded and not set later.
+%
+% We define \axo@pdfoutput and \axo@pdfliteral for our uses to have
+% function of \pdfoutput and \pdfliteral, but to be defined always.
+% We initialize them to a default suitable for dvi mode, and override
+% these definitions to cover the situations listed above. This needs
+% tests for whether \pdfoutput, \outputmode, etc are undefined of
+% defined. We put these inside a group, to evade the side effect that
+% \@ifundefined defines the object being tested.

+%
+% Here we make an interface, compatible with both: color.sty,
+% with the commands of axodraw v. 1, and with the commands of
+% colordvi.sty (used by axodraw v. 1).
+%
+% 1. We make a set of named colors suitable for use with both
+% axodraw's commands that take color arguments and with
+% color.sty's \color command.
+% 2. We define a command \SetColor to set a named color as the
+% current color. It is now identical to \color.
+% 3. For each of the colors that we define here, we make
+% named color setting commands, e.g., \Red
+% \textRed. \Red sets its (one) argument in Red, \textRed
+% is a "declaration" that changes the current color.
+% All the commands for setting color apply to both regular LaTeX
+% material and to axodraw objects. Their setting of color
+% respects LaTeX environments and TeX groups.
+%
+% We also define
+% a. Named-color commands like \textRed and \Red for named
+% colors to give the same interface as the colordvi
+% package (and hence axodraw v. 1).
+% b. \SetColor command to set a named color.
+
+
+\let\SetColor=\color
+
+% For v. 1 compatibility:
+\def\IfColor#1#2{#1}
+
+\newcommand\newcolor[2]{%
+ % Define a named color both in the color.sty style
+ % and in the colordvi.sty, with also a command giving the CMYK value.
+ % #1 is the color's name, #2 is its CMYK definition, space
+ % separated.
+ %
+ % Invoke color.sty's \definecolor after change of argument format:
+ \axo@new@color #1 #2\@%
+ % Define commands to use this color,
+ % E.g., if #1 is Red, then define \Red and \textRed:
+ \expandafter\def\csname #1\endcsname##1{{\SetColor{#1}##1}\ignorespaces}
+ \expandafter\def\csname text#1\endcsname{\SetColor{#1}\ignorespaces}
+ % The following to give the cmyk value of a color, e.g., \cmykRed,
+ % is no longer needed, since we no longer do color setting in
+ % postscript and pdf code:
+%% \expandafter\def\csname cmyk#1\endcsname{#2}

+% of our space-separated CMYK vector to a comma-separated vector:
+\def\axo@new@color #1 #2 #3 #4 #5\@{\definecolor{#1}{cmyk}{#2,#3,#4,#5}}
+
+
+% For consistency we define our named colors here, rather than
+% using color.sty's mechanisms. The
+% first 68 are standard colors, as defined by dvips, and
+% implemented in both colordvi.ps, and in color.sty with its
+% usenames and dvipsnames options (in the file dvipsnam.def
+% provided by the LaTeX graphics package).

+.SH NAME
+axohelp - helper program for use of LaTeX package axodraw2 with
+pdflatex.
+.SH SYNOPSIS
+.B axohelp [options] [filename]
+.SH DESCRIPTION
+Axohelp is a program used with the axodraw2, which is a LaTeX package
+for drawing Feynman graphs (and some other simple graphics) in LaTeX
+documents.
+
+When the axodraw2 package is used with pdflatex (or lualatex or
+xelatex) it creates a file with extension .ax1. This contains
+specifications of the graphics elements. Axohelp converts this to a
+file with extension ax2 that contains the necessary pdf code.
+The .ax2 file is read by pdflatex (etc) on its next run, and the
+contents of the .ax2 file are used in the final .pdf output file to
+draw the desired graphics.
+
+The files processed are specified as follows: When the filename on the
+command line is of the form file.ax1, then the input file is file.ax1
+and the output file is file.ax2. If the filename on the command line
+does not have extension .ax1, then this extension is appended.
+
+
+.SH OPTIONS
+Options can be introduced by single or double hyphen characters. The
+possible options are:
+
+.TP
+.B -h, --help
+Gives usage information
+
+.TP
+.B -v, --version
+Gives version information
+
+.TP
+.B -V
+NOT CURRENTLY IMPLEMENTED: Give information on each function used.
+
+.SH AUTHOR
+Current version, by John Collins (username jcc8 at node psu.edu) and
+Jos Vermaseren (username t68 at nikhef dot nl).
+
+The released version can be obtained from CTAN:
+<http://www.ctan.org/pkg/axodraw2/>, and an author's website

+ #[ About folds : (this line starts with one blank and two tabs)
+
+ The internals of the file have been organized in folds.
+ These are defined as a range of lines if which the first and last
+ lines have a special format. Each starts with any three characters
+ (may include tabs), then #[ for the start line and #] for the closing
+ line, then both lines need identical name fields, closed by a colon.
+ After the colon can be anything. When a fold is closed one should see
+ only the first line but with the #[ replaced by ## as in
+ ## About folds : (this line starts with one blank and two tabs)
+ Folds can be nested.
+ This fold concept comes originally from the occam compiler for the
+ transputer in the second half of the 1980's although there it was
+ implemented differently. It was taken over by the STedi editor in its
+ current form. The sources of this editor are available from the form
+ home site: http://www.nikhef.nl/~form
+ Some people have managed to emulate these folds in editors like emacs
+ and vim.

+\`configure' configures axohelp (TeX Live) 1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
