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 + +################################################################################ + +The LaTeX Project Public License +=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- + +LPPL Version 1.3c 2008-05-04 + +Copyright 1999 2002-2008 LaTeX3 Project + Everyone is allowed to distribute verbatim copies of this + license document, but modification of it is not allowed. + + +PREAMBLE +======== + +The LaTeX Project Public License (LPPL) is the primary license under +which the LaTeX kernel and the base LaTeX packages are distributed. + +You may use this license for any work of which you hold the copyright +and which you wish to distribute. This license may be particularly +suitable if your work is TeX-related (such as a LaTeX package), but +it is written in such a way that you can use it even if your work is +unrelated to TeX. + +The section `WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE', +below, gives instructions, examples, and recommendations for authors +who are considering distributing their works under this license. + +This license gives conditions under which a work may be distributed +and modified, as well as conditions under which modified versions of +that work may be distributed. + +We, the LaTeX3 Project, believe that the conditions below give you +the freedom to make and distribute modified versions of your work +that conform with whatever technical specifications you wish while +maintaining the availability, integrity, and reliability of +that work. If you do not see how to achieve your goal while +meeting these conditions, then read the document `cfgguide.tex' +and `modguide.tex' in the base LaTeX distribution for suggestions. + + +DEFINITIONS +=========== + +In this license document the following terms are used: + + `Work' + Any work being distributed under this License. + + `Derived Work' + Any work that under any applicable law is derived from the Work. + + `Modification' + Any procedure that produces a Derived Work under any applicable + law -- for example, the production of a file containing an + original file associated with the Work or a significant portion of + such a file, either verbatim or with modifications and/or + translated into another language. + + `Modify' + To apply any procedure that produces a Derived Work under any + applicable law. + + `Distribution' + Making copies of the Work available from one person to another, in + whole or in part. Distribution includes (but is not limited to) + making any electronic components of the Work accessible by + file transfer protocols such as FTP or HTTP or by shared file + systems such as Sun's Network File System (NFS). + + `Compiled Work' + A version of the Work that has been processed into a form where it + is directly usable on a computer system. This processing may + include using installation facilities provided by the Work, + transformations of the Work, copying of components of the Work, or + other activities. Note that modification of any installation + facilities provided by the Work constitutes modification of the Work. + + `Current Maintainer' + A person or persons nominated as such within the Work. If there is + no such explicit nomination then it is the `Copyright Holder' under + any applicable law. + + `Base Interpreter' + A program or process that is normally needed for running or + interpreting a part or the whole of the Work. + + A Base Interpreter may depend on external components but these + are not considered part of the Base Interpreter provided that each + external component clearly identifies itself whenever it is used + interactively. Unless explicitly specified when applying the + license to the Work, the only applicable Base Interpreter is a + `LaTeX-Format' or in the case of files belonging to the + `LaTeX-format' a program implementing the `TeX language'. + + + +CONDITIONS ON DISTRIBUTION AND MODIFICATION +=========================================== + +1. Activities other than distribution and/or modification of the Work +are not covered by this license; they are outside its scope. In +particular, the act of running the Work is not restricted and no +requirements are made concerning any offers of support for the Work. + +2. You may distribute a complete, unmodified copy of the Work as you +received it. Distribution of only part of the Work is considered +modification of the Work, and no right to distribute such a Derived +Work may be assumed under the terms of this clause. + +3. You may distribute a Compiled Work that has been generated from a +complete, unmodified copy of the Work as distributed under Clause 2 +above, as long as that Compiled Work is distributed in such a way that +the recipients may install the Compiled Work on their system exactly +as it would have been installed if they generated a Compiled Work +directly from the Work. + +4. If you are the Current Maintainer of the Work, you may, without +restriction, modify the Work, thus creating a Derived Work. You may +also distribute the Derived Work without restriction, including +Compiled Works generated from the Derived Work. Derived Works +distributed in this manner by the Current Maintainer are considered to +be updated versions of the Work. + +5. If you are not the Current Maintainer of the Work, you may modify +your copy of the Work, thus creating a Derived Work based on the Work, +and compile this Derived Work, thus creating a Compiled Work based on +the Derived Work. + +6. If you are not the Current Maintainer of the Work, you may +distribute a Derived Work provided the following conditions are met +for every component of the Work unless that component clearly states +in the copyright notice that it is exempt from that condition. Only +the Current Maintainer is allowed to add such statements of exemption +to a component of the Work. + + a. If a component of this Derived Work can be a direct replacement + for a component of the Work when that component is used with the + Base Interpreter, then, wherever this component of the Work + identifies itself to the user when used interactively with that + Base Interpreter, the replacement component of this Derived Work + clearly and unambiguously identifies itself as a modified version + of this component to the user when used interactively with that + Base Interpreter. + + b. Every component of the Derived Work contains prominent notices + detailing the nature of the changes to that component, or a + prominent reference to another file that is distributed as part + of the Derived Work and that contains a complete and accurate log + of the changes. + + c. No information in the Derived Work implies that any persons, + including (but not limited to) the authors of the original version + of the Work, provide any support, including (but not limited to) + the reporting and handling of errors, to recipients of the + Derived Work unless those persons have stated explicitly that + they do provide such support for the Derived Work. + + d. You distribute at least one of the following with the Derived Work: + + 1. A complete, unmodified copy of the Work; + if your distribution of a modified component is made by + offering access to copy the modified component from a + designated place, then offering equivalent access to copy + the Work from the same or some similar place meets this + condition, even though third parties are not compelled to + copy the Work along with the modified component; + + 2. Information that is sufficient to obtain a complete, + unmodified copy of the Work. + +7. If you are not the Current Maintainer of the Work, you may +distribute a Compiled Work generated from a Derived Work, as long as +the Derived Work is distributed to all recipients of the Compiled +Work, and as long as the conditions of Clause 6, above, are met with +regard to the Derived Work. + +8. The conditions above are not intended to prohibit, and hence do not +apply to, the modification, by any method, of any component so that it +becomes identical to an updated version of that component of the Work as +it is distributed by the Current Maintainer under Clause 4, above. + +9. Distribution of the Work or any Derived Work in an alternative +format, where the Work or that Derived Work (in whole or in part) is +then produced by applying some process to that format, does not relax or +nullify any sections of this license as they pertain to the results of +applying that process. + +10. a. A Derived Work may be distributed under a different license + provided that license itself honors the conditions listed in + Clause 6 above, in regard to the Work, though it does not have + to honor the rest of the conditions in this license. + + b. If a Derived Work is distributed under a different license, that + Derived Work must provide sufficient documentation as part of + itself to allow each recipient of that Derived Work to honor the + restrictions in Clause 6 above, concerning changes from the Work. + +11. This license places no restrictions on works that are unrelated to +the Work, nor does this license place any restrictions on aggregating +such works with the Work by any means. + +12. Nothing in this license is intended to, or may be used to, prevent +complete compliance by all parties with all applicable laws. + + +NO WARRANTY +=========== + +There is no warranty for the Work. Except when otherwise stated in +writing, the Copyright Holder provides the Work `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 Work is with you. Should the Work prove defective, you assume +the cost of all necessary servicing, repair, or correction. + +In no event unless required by applicable law or agreed to in writing +will The Copyright Holder, or any author named in the components of the +Work, or any other party who may distribute and/or modify the Work as +permitted above, be liable to you for damages, including any general, +special, incidental or consequential damages arising out of any use of +the Work or out of inability to use the Work (including, but not limited +to, loss of data, data being rendered inaccurate, or losses sustained by +anyone as a result of any failure of the Work to operate with any other +programs), even if the Copyright Holder or said author or said other +party has been advised of the possibility of such damages. + + +MAINTENANCE OF THE WORK +======================= + +The Work has the status `author-maintained' if the Copyright Holder +explicitly and prominently states near the primary copyright notice in +the Work that the Work can only be maintained by the Copyright Holder +or simply that it is `author-maintained'. + +The Work has the status `maintained' if there is a Current Maintainer +who has indicated in the Work that they are willing to receive error +reports for the Work (for example, by supplying a valid e-mail +address). It is not required for the Current Maintainer to acknowledge +or act upon these error reports. + +The Work changes from status `maintained' to `unmaintained' if there +is no Current Maintainer, or the person stated to be Current +Maintainer of the work cannot be reached through the indicated means +of communication for a period of six months, and there are no other +significant signs of active maintenance. + +You can become the Current Maintainer of the Work by agreement with +any existing Current Maintainer to take over this role. + +If the Work is unmaintained, you can become the Current Maintainer of +the Work through the following steps: + + 1. Make a reasonable attempt to trace the Current Maintainer (and + the Copyright Holder, if the two differ) through the means of + an Internet or similar search. + + 2. If this search is successful, then enquire whether the Work + is still maintained. + + a. If it is being maintained, then ask the Current Maintainer + to update their communication data within one month. + + b. If the search is unsuccessful or no action to resume active + maintenance is taken by the Current Maintainer, then announce + within the pertinent community your intention to take over + maintenance. (If the Work is a LaTeX work, this could be + done, for example, by posting to comp.text.tex.) + + 3a. If the Current Maintainer is reachable and agrees to pass + maintenance of the Work to you, then this takes effect + immediately upon announcement. + + b. If the Current Maintainer is not reachable and the Copyright + Holder agrees that maintenance of the Work be passed to you, + then this takes effect immediately upon announcement. + + 4. If you make an `intention announcement' as described in 2b. above + and after three months your intention is challenged neither by + the Current Maintainer nor by the Copyright Holder nor by other + people, then you may arrange for the Work to be changed so as + to name you as the (new) Current Maintainer. + + 5. If the previously unreachable Current Maintainer becomes + reachable once more within three months of a change completed + under the terms of 3b) or 4), then that Current Maintainer must + become or remain the Current Maintainer upon request provided + they then update their communication data within one month. + +A change in the Current Maintainer does not, of itself, alter the fact +that the Work is distributed under the LPPL license. + +If you become the Current Maintainer of the Work, you should +immediately provide, within the Work, a prominent and unambiguous +statement of your status as Current Maintainer. You should also +announce your new status to the same pertinent community as +in 2b) above. + + +WHETHER AND HOW TO DISTRIBUTE WORKS UNDER THIS LICENSE +====================================================== + +This section contains important instructions, examples, and +recommendations for authors who are considering distributing their +works under this license. These authors are addressed as `you' in +this section. + +Choosing This License or Another License +---------------------------------------- + +If for any part of your work you want or need to use *distribution* +conditions that differ significantly from those in this license, then +do not refer to this license anywhere in your work but, instead, +distribute your work under a different license. You may use the text +of this license as a model for your own license, but your license +should not refer to the LPPL or otherwise give the impression that +your work is distributed under the LPPL. + +The document `modguide.tex' in the base LaTeX distribution explains +the motivation behind the conditions of this license. It explains, +for example, why distributing LaTeX under the GNU General Public +License (GPL) was considered inappropriate. Even if your work is +unrelated to LaTeX, the discussion in `modguide.tex' may still be +relevant, and authors intending to distribute their works under any +license are encouraged to read it. + +A Recommendation on Modification Without Distribution +----------------------------------------------------- + +It is wise never to modify a component of the Work, even for your own +personal use, without also meeting the above conditions for +distributing the modified component. While you might intend that such +modifications will never be distributed, often this will happen by +accident -- you may forget that you have modified that component; or +it may not occur to you when allowing others to access the modified +version that you are thus distributing it and violating the conditions +of this license in ways that could have legal implications and, worse, +cause problems for the community. It is therefore usually in your +best interest to keep your copy of the Work identical with the public +one. Many works provide ways to control the behavior of that work +without altering any of its licensed components. + +How to Use This License +----------------------- + +To use this license, place in each of the components of your work both +an explicit copyright notice including your name and the year the work +was authored and/or last substantially modified. Include also a +statement that the distribution and/or modification of that +component is constrained by the conditions in this license. + +Here is an example of such a notice and statement: + + %% pig.dtx + %% Copyright 2005 M. Y. Name + % + % This work may be distributed and/or modified under the + % conditions of the LaTeX Project Public License, either version 1.3 + % of this license or (at your option) any later version. + % The latest version of this license is in + % http://www.latex-project.org/lppl.txt + % and version 1.3 or later is part of all distributions of LaTeX + % version 2005/12/01 or later. + % + % This work has the LPPL maintenance status `maintained'. + % + % The Current Maintainer of this work is M. Y. Name. + % + % This work consists of the files pig.dtx and pig.ins + % and the derived file pig.sty. + +Given such a notice and statement in a file, the conditions +given in this license document would apply, with the `Work' referring +to the three files `pig.dtx', `pig.ins', and `pig.sty' (the last being +generated from `pig.dtx' using `pig.ins'), the `Base Interpreter' +referring to any `LaTeX-Format', and both `Copyright Holder' and +`Current Maintainer' referring to the person `M. Y. Name'. + +If you do not want the Maintenance section of LPPL to apply to your +Work, change `maintained' above into `author-maintained'. +However, we recommend that you use `maintained', as the Maintenance +section was added in order to ensure that your Work remains useful to +the community even when you can no longer maintain and support it +yourself. + +Derived Works That Are Not Replacements +--------------------------------------- + +Several clauses of the LPPL specify means to provide reliability and +stability for the user community. They therefore concern themselves +with the case that a Derived Work is intended to be used as a +(compatible or incompatible) replacement of the original Work. If +this is not the case (e.g., if a few lines of code are reused for a +completely different task), then clauses 6b and 6d shall not apply. + + +Important Recommendations +------------------------- + + Defining What Constitutes the Work + + The LPPL requires that distributions of the Work contain all the + files of the Work. It is therefore important that you provide a + way for the licensee to determine which files constitute the Work. + This could, for example, be achieved by explicitly listing all the + files of the Work near the copyright notice of each file or by + using a line such as: + + % This work consists of all files listed in manifest.txt. + + in that place. In the absence of an unequivocal list it might be + impossible for the licensee to determine what is considered by you + to comprise the Work and, in such a case, the licensee would be + entitled to make reasonable conjectures as to which files comprise + the Work. diff --git a/Master/texmf-dist/doc/latex/tikz-swigs/README.md b/Master/texmf-dist/doc/latex/tikz-swigs/README.md new file mode 100644 index 00000000000..1f5a905a648 --- /dev/null +++ b/Master/texmf-dist/doc/latex/tikz-swigs/README.md @@ -0,0 +1,22 @@ +Ti*k*Z-SWIGs +============================================================= + +The `tikz-swigs` package provides horizontally and vertically split elliptical (pairs of) nodes in Ti*k*Z. + +The two new multi-part shapes are `swig hsplit` and `swig vsplit`.
