+ 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>.

+
+Basic Installation
+==================
+
+ These are generic installation instructions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system. If you're
+ using `csh' on an old version of System V, you might need to type
+ `sh ./configure' instead to prevent `csh' from trying to execute
+ `configure' itself.
+
+ Running `configure' takes awhile. While running, it prints some
+ messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation.
+
+ 5. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+ If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory. After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+ By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc. You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PATH'.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=PATH' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights. These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ d) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ e) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+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
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser 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 Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR

+dvisvgm -- A DVI to SVG converter
+
+DESCRIPTION
+
+ dvisvgm is a utility for TeX/LaTeX users. It converts
+ DVI files to the XML-based scalable vector graphics format SVG.
+
+
+DEPENDENCIES
+
+ dvisvgm relies on the following free libraries:
+ * FreeType 2 (http://www.freetype.org)
+ This library is used to extract glyph outlines
+ from PFB files.
+
+ * Ghostscript (http://pages.cs.wisc.edu/~ghost)
+ The PostScript special handler requires the Ghostscript
+ library libgs.so (Linux) or gsdll32.dll/gsdll64.dll (Windows)
+ to be installed. If the configure script finds the corresponding
+ Ghostscript development files on the system, it directly
+ links against libgs.so. Otherwise, the library is looked up
+ at runtime and PostScript support is enabled only if libgs.so
+ could be found.
+ Due to incompatible changes of the Ghostscript API, dvisvgm
+ requires Ghostscript 8.31 or later.
+
+ * kpathsea
+ This library is part of the Web2C package and is
+ usually installed in conjunction with a TeX distribution.
+ kpathsea provides functions for searching files in the
+ large texmf tree.
+
+ * potracelib (http://potrace.sourceforge.net)
+ Peter Selinger's bitmap tracing library is utilized to
+ vectorize Metafont's bitmap output.
+
+ * zlib (http://www.zlib.org)
+ Compressed SVG files are produced by using functions
+ of this library and the Gzstream wrapper classes
+ (http://www.cs.unc.edu/Research/compgeom/gzstream)
+ which are licensed under LGPL version 2.1 (or optionally any
+ later version) and should be included with this package.
+
+ If you want to build and run the testsuite located in the tests
+ subdirectory, you also need the googletest libraries
+ (http://code.google.com/p/googletest).
+
+
+COMPILATION
+
+ Quick installation info:
+ * type "./configure"
+ * type "make"
+ * type "make install" as root (or "sudo make install")
+
+ For generic configuration instructions see the file INSTALL.
+
+ The configure script should recognize all necessary parameters.
+ If a library is installed but not detected, specify its location
+ as commandline parameter of configure, e.g.
+ ./configure --with-freetype=/usr/local/freetype
+ (all available options can be displayed with ./configure --help)
+
+ The tracer module calls Metafont in case of lacking TFM or PFB files
+ via a system call. Please ensure that Metafont is installed and
+ reachable through the search path.
+
+ If you don't like compiling the sources yourself, you can
+ download pre-compiled executables for Windows and MiKTeX
+ from sourceforge.net instead (see below).
+
+
+USAGE
+ Information about the command-line interface and the available options
+ can be found in the manual page.
+
+
+ADDITIONAL INFORMATION
+ This package is available from CTAN (dviware/dvisvgm) and can
+ be downloaded from the project website at sourceforge.net as well:
+
+ http://dvisvgm.sourceforge.net
+
+ Here you can find the sources, pre-compiled binaries and further additional
+ information about the converter and related topics.
+
+ If you've found a bug, please let me know. You can either send me an
+ email or preferably use the bug tracker at Launchpad
+ (see https://launchpad.net/dvisvgm).

+.SH "NAME"
+dvisvgm \- converts DVI files to the XML\-based SVG format
+.SH "SYNOPSIS"
+.sp
+\fBdvisvgm\fR [ \fIoptions\fR ] \fIfile\fR [\&.dvi]
+.sp
+\fBdvisvgm\fR \-E [ \fIoptions\fR ] \fIfile\fR [\&.eps]
+.SH "DESCRIPTION"
+.sp
+The command\-line utility \fBdvisvgm\fR converts DVI files, as generated by TeX/LaTeX, to the XML\-based scalable vector graphics format SVG\&. Since the current SVG standard 1\&.1 doesn\(cqt specify multi\-page graphics, dvisvgm creates separate SVG files for each DVI page\&. Because of compatibility reasons, only the first page is converted by default\&. In order to select a different page or arbitrary page sequences, use option \fB\-p\fR which is described below\&.
+.sp
+dvisvgm should properly convert all pages that are made up of fonts and rules only\&. However, the utility also supports a couple of DVI extensions defined in terms of \fIDVI specials\fR\&. For a more detailed overview, see section \fBsupport of specials\fR below\&.
+.sp
+As SVG is a vector based graphics format, dvisvgm tries to convert the glyph outlines of all used fonts into scalable path descriptions\&. The fastest way to do that is to extract the path information from PFB (PostScript Type 1) files\&. So, if dvisvgm is able to find a PFB file for a required font, it will read the necessary information from this file\&.
+.sp
+TeX\(cqs main source for font descriptions is Metafont though, which produces bitmap output\&. That\(cqs why not all obtainable TeX fonts are available in PFB format\&. In these cases, dvisvgm tries to vectorize Metafont\(cqs output (GF fonts) by tracing the glyph bitmaps\&. The results are not as perfect as most (manually optimized) PFB outlines but are nonetheless really nice in most cases\&.
+.SH "OPTIONS"
+.PP
+\fB\-a, \-\-trace\-all\fR=[\fIretrace\fR]
+.RS 4
+This option forces dvisvgm to trace not only the actually needed glyphs but all glyphs of all bitmap fonts used in the DVI file\&. Since the tracing results are stored in the font cache, all following DVI conversions (without option
+\fB\-\-trace\-all\fR) where these fonts are involved, will be much faster\&. By default, dvisvgm traces only the actually needed glyphs, and adds them to the cache\&. The boolean option
+\fIretrace\fR
+determines how to handle glyphs already stored in the cache\&. By default, these glyphs are skipped\&. Setting argument
+\fIretrace\fR
+to
+\fIyes\fR
+or
+\fItrue\fR
+forces dvisvgm to trace the corresponding bitmaps again\&.
+.if n \{\

+.RS 4
+.it 1 an-trap
+.nr an-no-space-flag 1
+.nr an-break-flag 1
+.br
+.ps +1
+\fBNote\fR
+.ps -1
+.br
+This option only takes affect if font caching is active\&. Thus,
+\fB\-\-trace\-all\fR
+cannot be combined with option
+\fB\-\-cache=none\fR\&.
+.sp .5v
+.RE
+.RE
+.PP
+\fB\-b, \-\-bbox\fR=\fIfmt\fR
+.RS 4
+Sets the bounding box of the generated graphic to the specified format\&. The parameter
+\fIfmt\fR
+takes either one of the format specifiers listed below, or a sequence of four comma\- or whitespace\-separated length values
+\fIx1\fR,
+\fIy1\fR,
+\fIx2\fR
+and
+\fIy2\fR\&. The latter define two diagonal corners of the bounding box\&. Each length value consists of a floating point number and an optional length unit (pt, bp, cm, mm, in, or pc)\&. If the unit is omitted, TeX points (pt) are assumed\&.
+.sp
+It\(cqs also possible to give only one length value
+\fIl\fR\&. In this case, the minimal bounding box is computed and enlarged by adding (\-\fIl\fR,\-\fIl\fR) to the upper left and (\fIl\fR,\fIl\fR) to the lower right corner\&.
+.sp
+Alternatively, the following format specifiers are supported:
+.PP
+\fBInternational DIN/ISO paper sizes\fR
+.RS 4
+A\fIn\fR, B\fIn\fR, C\fIn\fR, D\fIn\fR, where
+\fIn\fR

+\fBPage orientation\fR
+.RS 4
+The default page orientation for DIN/ISO and American paper sizes is
+\fIportrait\fR, i\&.e\&.
+\fIwidth\fR
+<
+\fIheight\fR\&. Appending
+\fB\-landscape\fR
+or simply
+\fB\-l\fR
+to the format string switches to
+\fIlandscape\fR
+mode (\fIwidth\fR
+>
+\fIheight\fR)\&. For symmetry reasons you can also explicitly add
+\fB\-portrait\fR
+or
+\fB\-p\fR
+to indicate the default portrait format\&. Note that these suffixes are part of the size string and not separate options\&. Thus, they must directly follow the size specifier without additional blanks\&. Furthermore, the orientation suffixes can\(cqt be used with
+\fBdvi\fR,
+\fBmin\fR, and
+\fBnone\fR\&.

+.br
+Option
+\fB\-b, \-\-bbox\fR
+only affects the bounding box and does not transform the page content\&. Hence, if you choose a landscape format, the page won\(cqt be rotated\&.
+.sp .5v
+.RE
+.RE
+.PP
+\fB\-C, \-\-cache\fR[=\fIdir\fR]
+.RS 4
+To speed up the conversion process of bitmap fonts, dvisvgm saves intermediate conversion information in cache files\&. By default, these files are stored in $HOME/\&.dvisvgm/cache\&. If you prefer a different location, use option
+\fB\-\-cache\fR
+to overwrite the default\&. Furthermore, it is also possible to disable the font caching mechanism completely with option
+\fB\-\-cache=none\fR\&. If argument
+\fIdir\fR
+is omitted, dvisvgm prints the path of the default cache directory and some information about the stored fonts\&. Additionally, outdated and corrupted cache files are removed\&.
+.RE
+.PP
+\fB\-\-color\fR
+.RS 4
+Enables colorization of messages printed during the conversion process\&. The colors can be customized via the environment variable
+DVISVGM_COLORS\&. See the ENVIRONMENT section below for further information\&.
+.RE
+.PP
+\fB\-E, \-\-eps\fR
+.RS 4
+If this option is given, dvisvgm does not expect a DVI but an EPS input file, and tries to convert it to SVG\&. In order to do so, a single
+\fIpsfile\fR
+special command is created and forwarded to the PostScript special handler\&. This option is only available if dvisvgm was built with PostScript support enabled, and requires Ghostscript to be available\&. See option
+\fB\-\-libgs\fR
+for further information\&.
+.RE
+.PP
+\fB\-e, \-\-exact\fR
+.RS 4
+If this option is given, dvisvgm computes the precise bounding box of each character\&. By default, the values stored in a font\(cqs TFM file are used to determine a glyph\(cqs extent\&. As these values are intended to realize optimal character placements and are not designed to represent the exact dimensions, they don\(cqt necessarily correspond with the bounds of the visual glyphs\&. Thus, width and/or height of some glyphs may be larger than the respective TFM values\&. As a result, this can lead to clipped characters at the bounds of the SVG graphic\&. With option
+\fB\-\-exact\fR, dvisvgm analyzes the actual shape of each character and derives a usually tight bounding box\&.
+.RE
+.PP
+\fB\-m, \-\-fontmap\fR=\fIfilenames\fR
+.RS 4
+Loads and evaluates a single or multiple font map files\&. These files are required to resolve font file names and encodings\&. dvisvgm does not provide its own map file but tries to read available ones coming with dvips or dvipdfm\&. If option
+\fB\-\-fonrmapm\fR
+is not given, dvisvgm looks for the default map files
+ps2pk\&.map,
+dvipdfm\&.map, and
+psfonts\&.map
+(in this order)\&. Otherwise, the listed files are used\&. Multiple filenames must be separated by commas without leading and/or trailing whitespace\&. The map files are evaluated in the given order\&. By default, redefined mappings do not replace previous ones\&. However, each filename can be preceded by an optional mode specifier (\fB+\fR,
+\fB\-\fR, or
+\fB=\fR) to change this behavior:
+.PP
++mapfile
+.RS 4
+Only those entries in the given map file that don\(cqt redefine a font mapping are applied\&. That\(cqs also the default mode if no mode specifier is given\&.
+.RE
+.PP
+\-mapfile
+.RS 4
+Ensures that none of the font mappings defined in the given map file are used, i\&.e\&. previously defined mappings for the specified fonts are removed\&.
+.RE
+.PP
+=mapfile
+.RS 4
+All mappings defined in the map file are applied\&. Previously defined settings for the same font are replaced\&.
+.sp
+If the first filename in the filename sequence is preceded by a mode specifier, dvisvgm loads the default font map (see above) and applies the other map files afterwards\&. Otherwise, none of default map files will be loaded automatically\&.
+.sp
+Examples:
+\fB\-\-fontmap=myfile1\&.map,+myfile2\&.map\fR
+loads
+myfile1\&.map
+followed by
+myfile2\&.map
+where all redefinitions of
+myfile2\&.map
+are ignored\&.
+\fB\-\-fontmap==myfile1\&.map,\-myfile2\&.map\fR
+loads the default map file followed by
+myfile1\&.map
+and
+myfile2\&.map
+where all redefinitions of
+myfile1\&.map
+replace previous entries\&. Afterwards, all definitions for the fonts given in
+myfile2\&.map
+are removed again\&.
+.sp
+For further information about the map file formats, see the manuals of dvips and dvipdfm\&.
+.RE
+.RE
+.PP
+\fB\-h, \-\-help\fR[=\fImode\fR]
+.RS 4
+Prints a short summary of all available command\-line options\&. The optional
+\fImode\fR
+parameter is an integer value between 0 and 2\&. It selects the display variant of the help text\&. Mode 0 lists all options divided into categories with section headers\&. This is also the default if dvisvgm is called without parameters\&. Mode 1 lists all options ordered by the short option name, while mode 2 sorts the lines by the long option name\&.
+.RE
+.PP
+\fB\-\-keep\fR
+.RS 4
+Disables the removal of temporary files as created by Metafont (usually \&.gf, \&.tfm, and \&.log files)\&.
+.RE
+.PP
+\fB\-\-libgs\fR=\fIfilename\fR
+.RS 4
+This option is only available if the Ghostscript library is not directly linked to dvisvgm and if PostScript support was not completely disabled during compilation\&. In this case, dvisvgm tries to load the shared GS library dynamically during runtime\&. By default, it expects the library\(cqs name to be libgs\&.so (on Unix\-like systems) or gsdll32\&.dll/gsdll64\&.dll (Windows)\&. Option
+\fB\-\-libgs\fR
+can be used to give a different name\&. Alternatively, it\(cqs also possible to set the GS library name by the environment variable
+LIBGS\&. The latter has less precedence than the command\-line option\&.
+.RE
+.PP
+\fB\-L, \-\-linkmark\fR=\fItype\fR
+.RS 4
+Selects the method how to mark hyperlinked areas\&. The
+\fItype\fR
+argument can take one of the values
+\fInone\fR,
+\fIbox\fR, and
+\fIline\fR, where the latter is the default, i\&.e\&. all links are underlined when dvisvgm is called without option
+\fB\-\-linkmark\fR\&. Type
+\fIbox\fR
+draws a rectangle around the linked area, and
+\fInone\fR
+tells dvisvgm not to add any visible objects to hyperlinks\&.
+.RE
+.PP
+\fB\-l, \-\-list\-specials\fR
+.RS 4
+Prints a list of registered special handlers and exits\&. Each handler processes a set of special statements belonging to the same category\&. In most cases, the categories are identified by the prefix of the special statements\&. It\(cqs usually a leading word separated from the rest of the statement by a colon or a blank, e\&.g\&.
+\fIcolor\fR
+or
+\fIps\fR\&.
+.RE
+.PP
+\fB\-M, \-\-mag\fR=\fIfactor\fR
+.RS 4
+Sets the magnification factor applied in conjunction with Metafont calls prior tracing the glyphs\&. The larger this value, the better the tracing results\&. Nevertheless, large magnification values can cause Metafont arithmetic errors due to number overflows\&. So, use this option with care\&. The default setting usually produces nice results\&.
+.RE
+.PP
+\fB\-\-no\-mktexmf\fR
+.RS 4
+Suppresses the generation of missing font files\&. If dvisvgm can\(cqt find a font file through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by\&. This option disables these calls\&.
+.RE
+.PP
+\fB\-n, \-\-no\-fonts\fR[=\fIvariant\fR]
+.RS 4
+If this option is given, dvisvgm doesn\(cqt create SVG
+\fIfont\fR
+elements but uses
+\fIpaths\fR
+instead\&. The resulting SVG files tends to be larger but concurrently more compatible with most applications that don\(cqt support SVG fonts yet\&. The optional argument
+\fIvariant\fR
+selects the method how to substitute fonts by paths\&. Variant 0 creates
+\fIpath\fR
+and
+\fIuse\fR
+elements\&. Variant 1 creates
+\fIpath\fR
+elements only\&. Option
+\fB\-\-no\-fonts\fR

+\fB\-\-no\-styles\fR\&.

+\fB\-c, \-\-scale\fR=\fIsx\fR[,\fIsy\fR]
+.RS 4

+dvisvgm - converts DVI files to the XML-based SVG format
+
+
+SYNOPSIS
+--------
+*dvisvgm* [ 'options' ] 'file' [.dvi]
+
+*dvisvgm* -E [ 'options' ] 'file' [.eps]
+
+
+DESCRIPTION
+-----------
+The command-line utility *dvisvgm* converts DVI files, as generated by TeX/LaTeX, to the
+XML-based scalable vector graphics format SVG. Since the current SVG standard 1.1 doesn't
+specify multi-page graphics, dvisvgm creates separate SVG files for each DVI page.
+Because of compatibility reasons, only the first page is converted by default. In order
+to select a different page or arbitrary page sequences, use option *-p* which is described below.
+
+dvisvgm should properly convert all pages that are made up of fonts and rules only.
+However, the utility also supports a couple of DVI extensions defined in terms of 'DVI specials'.
+For a more detailed overview, see section *support of specials* below.
+
+As SVG is a vector based graphics format, dvisvgm tries to convert the glyph
+outlines of all used fonts into scalable path descriptions. The fastest way to do that
+is to extract the path information from PFB (PostScript Type 1) files. So, if dvisvgm is able
+to find a PFB file for a required font, it will read the necessary information from this file.
+
+TeX's main source for font descriptions is Metafont though, which produces bitmap output. That's why
+not all obtainable TeX fonts are available in PFB format. In these cases, dvisvgm tries
+to vectorize Metafont's output (GF fonts) by tracing the glyph bitmaps. The results are not
+as perfect as most (manually optimized) PFB outlines but are nonetheless really nice in most cases.
+
+
+OPTIONS
+-------
+*-a, --trace-all*=['retrace']::
+This option forces dvisvgm to trace not only the actually needed glyphs but all
+glyphs of all bitmap fonts used in the DVI file. Since the tracing results are stored in
+the font cache, all following DVI conversions (without option *--trace-all*) where these
+fonts are involved, will be much faster. By default, dvisvgm traces only the actually
+needed glyphs, and adds them to the cache.
+The boolean option 'retrace' determines how to handle glyphs already stored in the cache.
+By default, these glyphs are skipped. Setting argument 'retrace' to 'yes' or
+'true' forces dvisvgm to trace the corresponding bitmaps again.
++
+[NOTE]
+This option only takes affect if font caching is active. Thus, *--trace-all* cannot be
+combined with option *--cache=none*.
++
+
+
+*-b, --bbox*='fmt'::
+Sets the bounding box of the generated graphic to the specified format. The parameter 'fmt'
+takes either one of the format specifiers listed below, or a sequence of four comma- or
+whitespace-separated length values 'x1', 'y1', 'x2' and 'y2'. The latter define two diagonal
+corners of the bounding box. Each length value consists of a floating point number and an optional
+length unit (pt, bp, cm, mm, in, or pc). If the unit is omitted, TeX points (pt) are assumed.
++
+It's also possible to give only one length value 'l'. In this case, the minimal bounding box
+is computed and enlarged by adding (-'l',-'l') to the upper left and ('l','l') to the lower
+right corner.
++
+Alternatively, the following format specifiers are supported:
+
+ *International DIN/ISO paper sizes*;;
+ A__n__, B__n__, C__n__, D__n__, where 'n' is a non-negative integer, e.g. A4 or a4 for DIN/ISO A4
+ format (210mm &#215; 297mm).
+
+ *North American paper sizes*;;
+ invoice, executive, legal, letter, ledger
+
+ *Special bounding box sizes*;;
+[horizontal]
+ *dvi*::: page size stored in the DVI file
+ *min*::: computes the minimal/tightest bounding box
+ *none*::: no bounding box is assigned
+
+//
+ *Page orientation*;;
+ The default page orientation for DIN/ISO and American paper sizes is 'portrait',
+ i.e. 'width' < 'height'. Appending *-landscape* or simply *-l* to the format
+ string switches to 'landscape' mode ('width' > 'height'). For symmetry reasons you can
+ also explicitly add *-portrait* or *-p* to indicate the default portrait format.
+ Note that these suffixes are part of the size string and not separate options. Thus,
+ they must directly follow the size specifier without additional blanks.
+ Furthermore, the orientation suffixes can't be used with *dvi*, *min*, and *none*.
++
+[NOTE]
+Option *-b, --bbox* only affects the bounding box and does not transform the page content.
+Hence, if you choose a landscape format, the page won't be rotated.
++
+//
+
+//
+*-C, --cache*[='dir']::
+To speed up the conversion process of bitmap fonts, dvisvgm saves intermediate conversion
+information in cache files. By default, these files are stored in $HOME/.dvisvgm/cache. If you prefer
+a different location, use option *--cache* to overwrite the default. Furthermore, it is also possible
+to disable the font caching mechanism completely with option *--cache=none*. If argument 'dir' is omitted,
+dvisvgm prints the path of the default cache directory and some information about the stored fonts.
+Additionally, outdated and corrupted cache files are removed.
+
+
+*--color*::
+Enables colorization of messages printed during the conversion process. The colors can be customized
+via the environment variable +DVISVGM_COLORS+. See the ENVIRONMENT section below for further information.
+
+
+*-E, --eps*::
+If this option is given, dvisvgm does not expect a DVI but an EPS input file, and tries to convert
+it to SVG. In order to do so, a single 'psfile' special command is created and forwarded to the
+PostScript special handler.
+This option is only available if dvisvgm was built with PostScript support enabled, and requires
+Ghostscript to be available. See option *--libgs* for further information.
+
+
+*-e, --exact*::
+If this option is given, dvisvgm computes the precise bounding box of each character. By default,
+the values stored in a font's TFM file are used to determine a glyph's extent. As these values are
+intended to realize optimal character placements and are not designed to represent the exact dimensions,
+they don't necessarily correspond with the bounds of the visual glyphs. Thus, width and/or height
+of some glyphs may be larger than the respective TFM values. As a result, this can lead to clipped
+characters at the bounds of the SVG graphic. With option *--exact*, dvisvgm analyzes the actual shape
+of each character and derives a usually tight bounding box.
+
+
+*-m, --fontmap*='filenames'::
+Loads and evaluates a single or multiple font map files. These files are required to resolve
+font file names and encodings. dvisvgm does not provide its own map file but tries to read
+available ones coming with dvips or dvipdfm. If option *--fonrmapm* is not given, dvisvgm looks for the
+default map files +ps2pk.map+, +dvipdfm.map+, and +psfonts.map+ (in this order). Otherwise, the
+listed files are used. Multiple filenames must be separated by commas without leading and/or trailing
+whitespace.
+The map files are evaluated in the given order. By default, redefined mappings do not replace previous ones.
+However, each filename can be preceded by an optional mode specifier (*+*, *-*, or *=*) to change this behavior:
+
+ +mapfile;;
+ Only those entries in the given map file that don't redefine a font mapping are applied.
+ That's also the default mode if no mode specifier is given.
+
+ -mapfile;;
+ Ensures that none of the font mappings defined in the given map file are used, i.e. previously
+ defined mappings for the specified fonts are removed.
+
+ =mapfile;;
+ All mappings defined in the map file are applied. Previously defined settings for the same font
+ are replaced.
++
+If the first filename in the filename sequence is preceded by a mode specifier, dvisvgm loads the
+default font map (see above) and applies the other map files afterwards. Otherwise, none of default
+map files will be loaded automatically.
++
+Examples: *--fontmap=myfile1.map,+myfile2.map* loads `myfile1.map` followed by `myfile2.map` where all
+redefinitions of `myfile2.map` are ignored.
+*--fontmap==myfile1.map,-myfile2.map* loads the default map file followed by `myfile1.map` and `myfile2.map`
+where all redefinitions of `myfile1.map` replace previous entries. Afterwards, all definitions for the fonts
+given in `myfile2.map` are removed again.
++
+For further information about the map file formats, see the manuals of dvips and dvipdfm.
+
+
+*-h, --help*[='mode']::
+Prints a short summary of all available command-line options. The optional 'mode' parameter is
+an integer value between 0 and 2. It selects the display variant of the help text. Mode 0
+lists all options divided into categories with section headers. This is also the default if
+dvisvgm is called without parameters. Mode 1 lists all options ordered by the short option name,
+while mode 2 sorts the lines by the long option name.
+
+
+*--keep*::
+Disables the removal of temporary files as created by Metafont (usually .gf, .tfm, and .log files).
+
+
+*--libgs*='filename'::
+This option is only available if the Ghostscript library is not directly linked to dvisvgm and if
+PostScript support was not completely disabled during compilation. In this case, dvisvgm tries
+to load the shared GS library dynamically during runtime. By default, it expects the library's name
+to be libgs.so (on Unix-like systems) or gsdll32.dll/gsdll64.dll (Windows). Option *--libgs* can be
+used to give a different name. Alternatively, it's also possible to set the GS library name by the
+environment variable +LIBGS+. The latter has less precedence than the command-line option.
+
+
+*-L, --linkmark*='type'::
+Selects the method how to mark hyperlinked areas. The 'type' argument can take one of the values
+'none', 'box', and 'line', where the latter is the default, i.e. all links are underlined when
+dvisvgm is called without option *--linkmark*. Type 'box' draws a rectangle around the linked
+area, and 'none' tells dvisvgm not to add any visible objects to hyperlinks.
+
+
+*-l, --list-specials*::
+Prints a list of registered special handlers and exits. Each handler processes a set of special
+statements belonging to the same category. In most cases, the categories are identified by the
+prefix of the special statements. It's usually a leading word separated from the rest of the
+statement by a colon or a blank, e.g. 'color' or 'ps'.
+
+
+*-M, --mag*='factor'::
+Sets the magnification factor applied in conjunction with Metafont calls prior tracing the glyphs.
+The larger this value, the better the tracing results. Nevertheless, large magnification values
+can cause Metafont arithmetic errors due to number overflows. So, use this option with care.
+The default setting usually produces nice results.
+
+
+*--no-mktexmf*::
+Suppresses the generation of missing font files. If dvisvgm can't find a font file
+through the kpathsea lookup mechanism, it calls the external tools mktextfm or mktexmf by.
+This option disables these calls.
+
+
+*-n, --no-fonts*[='variant']::
+If this option is given, dvisvgm doesn't create SVG 'font' elements but uses 'paths' instead. The
+resulting SVG files tends to be larger but concurrently more compatible with most applications that
+don't support SVG fonts yet. The optional argument 'variant' selects the method how to substitute fonts
+by paths. Variant 0 creates 'path' and 'use' elements. Variant 1 creates 'path' elements only.
+Option *--no-fonts* implies *--no-styles*.
+
+
+*-c, --scale*='sx'[,'sy']::
+Scales the page content horizontally by 'sx' and vertically by 'sy'. This option is equivalent
+to *-TS*'sx','sy'.
+
+
+*-S, --no-specials*[='names']::
+Disable processing of special commands embedded in the DVI file. If no further
+parameter is given, all specials are ignored. To selectively disable sets of specials,
+an optional comma-separated list of names can be appended to this option. A 'name' is the unique
+identifier referencing the intended special handler. Option *--list-specials* lists all currently
+available handlers and their names.
+All unsupported special statements are silently ignored.
+
+
+*--no-styles*::
+By default, dvisvgm creates CSS styles and class attributes to reference fonts because it's more
+compact than repeatedly set the complete font information in each text element. However, if you
+prefer direct font references, the default behavior can be disabled with option *--no-styles*.
+
+
+*-o, --output*='pattern'::
+Sets the name pattern of the output file. Parameter 'pattern' is a string that may
+contain the variables *%f* and *%p*. *%f* stands for the base name of the DVI file, i.e.
+the DVI filename without suffix, and *%p* is the current page number.
+The default pattern is *%f-%p.svg* if the DVI file consists of more than one page, and
+*%f.svg* otherwise. That means, a DVI file 'foo.dvi' is converted to 'foo.svg' if 'foo.dvi'
+is a single-page document. Otherwise, multiple SVG files 'foo-01.svg', 'foo-02.svg', etc. are
+produced. In Windows environments, the percent sign indicates dereferenced environment
+variables, and must therefore be protected by a second percent sign, e.g. *--output=%%f-%%p*.
+
+
+*-p, --page*='ranges'::
+This option sets the pages to be processed. Parameter 'ranges' consists of a comma-separated list
+of single page numbers and/or page ranges. A page range is a pair of numbers separated by a hyphen,
+e.g. 5-12. Thus, a page sequence might look like this: 2-4,6,9-12,15. It doesn't matter if a page
+is given more than once or if page ranges overlap. dvisvgm always extracts the page numbers in
+ascending order and converts them only once.
+In order to stay compatible with previous versions, the default page sequence is 1. dvisvgm
+therefore converts only the first page and not the whole document in case option *--page* is omitted.
+Usually, page ranges consist of two numbers denoting the first and last page to be converted.
+If the conversion is to be started at page 1, or if it should continue up to the last DVI page, the
+first or second range number can be omitted, respectively. Example: *--page=-10* converts all
+pages up to page 10, *--page=10-* converts all pages starting with page 10.
+Please consider that the page values don't refer to the page numbers printed on the page.
+Instead, the physical page count is expected, where the first page always gets number 1.
+
+
+*-d, --precision*='digits'::
+Specifies the maximal number of decimal places applied to floating-point attribute values.
+All attribute values written to the generated SVG file(s) are rounded accordingly. The
+parameter 'digits' allows integer values from 0 to 6, where 0 enables the automatic selection
+of significant decimal places. This is also the default value if dvisvgm is called without
+option *--precision*.
+
+
+*-P, --progress*[='delay']::
+Enables a simple progress indicator shown when time-consuming operations like
+PostScript specials are processed. The indicator doesn't appear before the given
+delay (in seconds) has elapsed. The default delay value is 0.5 seconds.
+
+
+*-r, --rotate*='angle'::
+Rotates the page content clockwise by 'angle' degrees around the page center.
+This option is equivalent to *-TR*'angle'.
+
+
+*-s, --stdout*::
+Don't write the SVG output to a file but redirect it to *stdout*.
+
+
+*-T, --transform*='commands'::
+Applies a sequence of transformations to the SVG content. Each transformation is described
+by a 'command' beginning with a capital letter followed by a list of comma-separated
+parameters. Following transformation commands are supported:
+
+ *T* 'tx'[,'ty'];;
+ Translates (moves) the page in direction of vector ('tx','ty'). If 'ty' is omitted,
+ 'ty'=0 is assumed.
+ The expected unit length of 'tx' and 'ty' are TeX points (1pt = 1/72.27in). However, there
+ are several constants defined to simplify the unit conversion (see below).
+
+ *S* 'sx'[,'sy'];;
+ Scales the page horizontally by 'sx' and vertically by 'sy'. If 'sy' is omitted,
+ 'sy'='sx' is assumed.
+
+ *R* 'angle'[,'x','y'];;
+ Rotates the page clockwise by 'angle' degrees around point ('x','y'). If the optional
+ arguments 'x' and 'y' are omitted, the page will be rotated around its center depending on
+ the chosen page format. When option *-bnone* is given, the rotation center is origin (0,0).
+
+ *KX* 'angle';;
+ Skews the page along the 'x'-axis by 'angle' degrees. Argument 'angle' can take any value
+ except 90+180__k__, where 'k' is an integer.
+
+ *KY* 'angle';;
+ Skews the page along the 'y'-axis by 'angle' degrees. Argument 'angle' can take any value
+ except 90+180__k__, where 'k' is an integer.
+
+ *FH* ['y'];;
+ Mirrors (flips) the page at the horizontal line through point (0,'y'). Omitting the optional argument
+ leads to 'y'='h'/2, where 'h' denotes the page height (see 'pre-defined constants' below).
+
+ *FV* ['x'];;
+ Mirrors (flips) the page at the vertical line through point ('x',0). Omitting the optional argument
+ leads to 'x'='w'/2, where 'w' denotes the page width (see 'pre-defined constants' below).
+
+ *M* 'm1',...,'m6';;
+ Applies a transformation described by the 3&#215;3 matrix
+ \(('m1','m2','m3'),('m4','m5','m6'),(0,0,1)), where the inner triples denote
+ the rows.
++
+[NOTE]
+=================================================================================================
+All transformation commands of option *-T, --transform* are applied in the order of their appearance.
+Multiple commands can optionally be separated by spaces. In this case the whole transformation string
+has to be enclosed in double quotes. All parameters are expressions of floating point type. You can either
+give plain numbers or arithmetic terms combined by the operators *+* (addition), *-* (subtraction),
+*** (multiplication), */* (division) or *%* (modulo) with common associativity and
+precedence rules. Parentheses may be used as well.
+
+Additionally, some pre-defined constants are provided:
+
+[horizontal]
+*ux*:: horizontal position of upper left page corner in TeX point units
+*uy*:: vertical position of upper left page corner in TeX point units
+*h*:: page height in TeX point units (0 in case of *-bnone*)
+*w*:: page width in TeX point units (0 in case of *-bnone*)
+
+Furthermore, you can use the length constants *pt*, *mm*, *cm* and *in*, e.g.
++2cm+ or +1.6in+. Thus, option +-TT1in,0R45+ moves the page content 1 inch to the right and rotates it
+by 45 degrees around the page center afterwards.
+
+For single transformations you can also use options *-c*, *-t* and *-r*. Note that
+the order in which these options are given is not significant, i.e. you can't use them to describe
+transformation sequences. They are simply independent shorthand options for common transformations.
+
+=================================================================================================
++
+//
+
+//
+*-t, --translate*='tx'[,'ty']::
+Translates (moves) the page content in direction of vector ('tx','ty'). This option is
+equivalent to *-TT*'tx','ty'.
+
+
+*-v, --verbosity*='level'::
+Controls the type of messages printed during a dvisvgm run:
+[horizontal]
+ *0*;; no message output
+ *1*;; error messages only
+ *2*;; warning messages only
+ *4*;; informational messages only
+
++
+[NOTE]
+By adding these values you can combine the categories. The default level is 7, i.e. all
+messages are printed.
++
+
+
+*-V, --version*[='extended']::
+Prints the version of dvisvgm and exits. If the optional argument is set to 'yes', the
+version numbers of the linked libraries are printed as well.
+
+
+*-z, --zip*[='level']::
+Creates a compressed SVG file with suffix .svgz. The optional argument specifies the compression
+level. Valid values are in the range of 1 to 9 (default value is 9). Larger values cause better
+compression results but take more computation time.
++
+CAUTION: This option cannot be combined with *-s, --stdout*.
+
+
+SUPPORT OF SPECIALS
+-------------------
+dvisvgm supports several sets of 'special commands' that can be used to enrich DVI files with additional
+features, like color, graphics or hyperlinks. The evaluation of special commands is delegated to various handlers.
+Each handler is responsible for all special statements of the same command set, i.e. commands beginning
+with the same prefix. To get a list of actually provided special handlers, use option *--list-specials* (see above).
+
+*bgcolor*::
+Special statement for changing the background/page color. Since SVG 1.1 doesn't support background colors,
+dvisvgm inserts a rectangle of the chosen color into the generated SVG document. This rectangle always gets
+the same size as the selected or computed bounding box. This background color command is part of the color
+special set but is handled separately in order to let the user turn it off. For an overview of the command
+syntax, see the documentation of dvips, for instance.
+
+*color*::
+Statements of this command set provide instructions to change the text/paint color. For an overview of the
+exact syntax, see the documentation of dvips, for instance.
+
+*dvisvgm*::
+dvisvgm offers its own small set of specials. The following list gives a brief overview.
+ *dvisvgm:raw* 'text';;
+ Adds an arbitrary sequence of characters to the SVG output. dvisvgm does not perform any validation here,
+ thus the user has to ensure that the resulting SVG is still valid. Parameter 'text' may
+ contain the macros *{?x}*, *{?y}*, and *{?color}* that are expanded to the current 'x' or 'y' coordinate
+ and the current color, respectively. Also, macro *{?nl}* expands to a newline character.
+
+ *dvisvgm:img* 'width' 'height' 'file';;
+ Creates an image element at the current graphic position referencing the given file. JPEG, PNG, and SVG images
+ can be used here. However, dvisvgm does not check the file format or the file name suffix. The lengths 'width'
+ and 'height' must be given as plain floating point numbers in TeX point units (1in = 72.27pt).
+
+ *dvisvgm:bbox* n[ew] 'name';;
+ Defines or resets a local bounding box called 'name'. The name may consist of letters and digits.
+ While processing a DVI page, dvisvgm continuously updates the (global) bounding box of the current page in order to
+ determine the minimal rectangle containing all visible page components (characters, images, drawing elements etc.)
+ Additionally to the global bounding box, the user can request an arbitrary number of named local bounding boxes.
+ Once defined, these boxes are updated together with the global bounding box starting with the first character that
+ follows the definition. Thus, the local boxes can be used to compute the extent of parts of the page. This is useful
+ for scenarios where the generated SVG file is post-processed.
+ In conjunction with special dvisvgm:raw, the macro *{?bbox 'name'}* expands to the four values 'x', 'y', 'w', and 'h'
+ (separated by spaces) specifying the coordinates of the upper left corner, width, and height of the local box 'name'.
+ If box 'name' wasn't previously defined, all four values equal zero.
+
+ *dvisvgm:bbox* 'width' 'height' ['depth'];;
+ Updates the bounding box of the current page by embedding a virtual rectangle ('x', 'y', 'width', 'height')
+ where the lower left corner is located at the current DVI drawing position ('x','y'). If the optional parameter 'depth'
+ is specified, dvisvgm embeds a second rectangle ('x', 'y', 'width', -__depth__). The lengths 'width', 'height' and
+ 'depth' must be given as plain floating point numbers in TeX point units (1in = 72.27pt). Depending on size and position
+ of the virtual rectangle, this command either enlarges the overall bounding box or leaves it as is. It's not possible
+ to reduce its extent. This special should be used in conjunction with *dvisvgm:raw* in order to update the viewport
+ of the page properly.
+
+ *dvisvgm:bbox* a[bs] 'x1' 'y1' 'x2' 'y2';;
+ This variant of the bbox special updates the bounding box by embedding a virtual rectangle ('x1','y1','x2','y2').

+ This variant of the bbox special assigns an absolute (final) bounding box to the resulting SVG. After executing
+ this command, dvisvgm doesn't further alter the bounding box coordinates, except this special is called again later.
+ The points ('x1','y1') and ('x2','y2') denote two diagonal corners of the rectangle given in TeX point units.
++
+The following TeX snippet adds two raw SVG elements to the output and updates the bounding box accordingly:
++
+------------------------------------------------------------------------------------
+\special{dvisvgm:raw <circle cx='{?x}' cy='{?y}' r='10' stroke='black' fill='red'/>}
+\special{dvisvgm:bbox 20 10 10}
+
+\special{dvisvgm:raw <path d='M50 200 L10 250 H100 Z' stroke='black' fill='blue'/>}
+\special{dvisvgm:bbox abs 10 200 100 250}
+------------------------------------------------------------------------------------
++
+
+*em*::
+These specials were introduced with the emTeX distribution by Eberhard Mattes. They provide line drawing
+statements, instructions for embedding MSP, PCX, and BMP image files, as well as two PCL commands.
+dvisvgm supports only the line drawing statements and ignores all other em specials silently.
+A description of the command syntax can be found in the DVI driver documentation coming with emTeX (see CTAN).
+
+*html*::
+The hyperref specials allow the definition of hyperlinks inside DVI files in various flavors. dvisvgm supports
+the plain HyperTeX special constructs as created with hyperref package option 'hypertex'. Internal links, i.e.
+references to other parts of the same document, are only converted if the link and the corresponding link target
+are located on the same page. Links between different pages are not supported yet.
+By default, all linked areas of the document are underlined. Option *--linkmark* allows to change this behavior.
+See above for further details. Information on syntax and semantics of the HyperTeX specials can be found in the
+hyperref manual.
+
+*pdf*::
+pdfTeX and dvipdfmx introduced several special commands related to the generation of PDF files. Currently, only
+two of them, 'pdf:mapfile' and 'pdf:mapline' are supported by dvisvgm. These specials allow modifying the font map
+tree during the processing of DVI files. They are used by CTeX, for example. dvisvgm supports both, the dvips and
+dvipdfm font map format. For further information on the command syntax and semantics, see the documentation of
+\pdfmapfile in the pdfTeX user manual.
+
+*ps*::
+The famous DVI driver dvips introduced its own set of specials in order to embed PostScript code into DVI files,
+which greatly improves the capabilities of DVI documents. One aim of dvisvgm is to completely evaluate all
+PostScript snippets and to convert a large amount of it to SVG. However, in contrast to dvips, dvisvgm uses floating point
+arithmetics to compute the precise position of each graphic element, i.e. it doesn't round the coordinates. Therefore,
+the relative locations of the graphic elements may slightly differ from those computed by dvips.
++
+Since PostScript is a rather complex language, dvisvgm does not try to implement its own PostScript interpreter but relies on
+Ghostscript instead. If the Ghostscript library was not linked while building dvisvgm, it is looked up and loaded dynamically
+during runtime. In this case, dvisvgm looks for 'libgs.so' on Unix-like systems, and for 'gsdll32.dll' or 'gsdll64.dll' on Windows.
+You can override these default file names with environment variable +LIBGS+ or the command-line option *--libgs*.
+The library must be installed and reachable through the ld search path (\*nix) or the PATH environment
+variable (Windows). If it cannot be found, the processing of PostScript specials is disabled.
+Use option *--list-specials* to check whether PS support is available, i.e. the entry 'ps' is present.
+
+*tpic*::
+The TPIC special set defines instructions for drawing simple geometric objects. Some LaTeX packages, like
+eepic and tplot, use these specials to describe graphics.
+
+
+EXAMPLES
+--------
+--------------
+dvisvgm file
+--------------
+Converts the first page of 'file.dvi' to 'file.svg'.
+
+---------------
+dvisvgm -z file
+---------------
+Converts the first page of 'file.dvi' to 'file.svgz' with default compression level 9.
+
+-------------------------------------
+dvisvgm -p5 -z3 -ba4-l -onewfile file
+-------------------------------------
+Converts the fifth page of 'file.dvi' to 'newfile.svgz' with compression level 3.
+The bounding box is set to DIN/ISO A4 in landscape format.
+
+-----------------------------------------------------
+dvisvgm --transform="R20,w/3,2h/5 T1cm,1cm S2,3" file
+-----------------------------------------------------
+Converts the first page of 'file.dvi' to 'file.svg' where three transformations are applied.
+
+
+ENVIRONMENT
+-----------
+dvisvgm uses the *kpathsea* library for locating the files that it opens.
+Hence, the environment variables described in the library's documentation influence the converter.
+
+If dvisvgm was linked without the Ghostscript library, and if PostScript support has not been disabled,
+the shared Ghostscript library is looked up during runtime via dlopen(). The environment variable +LIBGS+
+can be used to specify path and file name of the library.
+
+The pre-compiled Windows versions of dvisvgm require a working installation of MiKTeX 2.9 or above.
+dvisvgm does not work together with the portable edition of MiKTeX because it relies on MiKTeX's COM
+interface only accessible in a local installation.
+To enable the evaluation of PostScript specials, the original Ghostscript DLL 'gsdll32.dll' must be present
+and reachable through the search path. 64-bit Windows builds require the 64-bit Ghostscript DLL 'gsdll64.dll'.
+Both DLLs come with the corresponding Ghostscript installers available from www.ghostscript.com.
+
+The environment variable +DVISVGM_COLORS+ specifies the colors used to highlight various parts of dvisvgm's
+message output. It is only evaluated if option *--color* is given. The value of +DVISVGM_COLORS+ is a list of
+colon-separated entries of the form 'gg'='BF', where 'gg' denotes one of the color group indicators listed
+below, and 'BF' are two hexadecimal digits specifying the background (first digit) and foreground/text color
+(second digit). The color color values are defined as follows: 0=black, 1=red, 2=green, 3=yellow, 4=blue,
+5=magenta, 6=cyan, 7=gray, 8=bright red, 9=bright green, A=bright yellow, B=bright blue, C=bright magenta,
+D=bright cyan, E=bright gray, F=white. Depending on the terminal, the colors may differ. Rather than changing
+both the text and background color, it's also possible to change only one of them: An asterisk (*) in
+place of a hexadecimal digit indicates the default text or background color of the terminal.
+
+All malformed entries in the list are silently ignored.
+
+[horizontal]
+*er*:: error messages
+*wn*:: warning messages
+*pn*:: messages about page numbers
+*ps*:: page size messages
+*fw*:: information about the files written
+*sm*:: state messages
+*tr*:: messages of the glyph tracer
+*pi*:: progress indicator
+
+*Example:* +er=01:pi=\*5+ sets the colors of error messages (+er+) to red (+1+) on black (+0+), and those
+of progress indicators (+pi+) to cyan (+5+) on default background (+*+).
