License: GPL-3+ Comment: The groff manual is also distributed under the terms of the GNU Free Documentation License version 1.3. On Debian systems, this is available in /usr/share/common-licenses/GFDL-1.3 as part of the base-files package. However, Debian does not consider this free when the Front-Cover Texts or Back-Cover Texts options are used. groff is distributed with a LICENSES file containing the following text (excerpted): . The groff program is a free software project. It is licensed under the GNU General Public License (GNU GPL), version 3 or later. . The file COPYING in the top directory of the groff source package contains a copy of the GPL that was downloaded from the GNU web site http://www.gnu.org/copyleft/gpl.txt at 3 jan 2009. . All files part of groff are licensed under this version of the GPL (or licenses which are compatible with the GPL). You are free to choose version 3 or any subsequent version of the GPL. . I e-mailed the upstream maintainer to clarify the intent of this. Here is the relevant part of the reply: . From: Werner LEMBERG To: cjwatson@debian.org Subject: Re: Clarifying the scope of groff/LICENSE Date: Thu, 18 Nov 2004 00:19:52 +0100 (CET) . > Since "compatible with the GPL" means to all intents and purposes > "may be distributed under the terms of the GPL", can I correctly > assume that groff/LICENSE grants me permission to distribute > groff/doc/groff.texinfo and groff/doc/pic.ms under the terms of the > GPL? .

I haven't found time to revert the FDL stuff back to GPL. It basically affects only Bernd Warken and me, and we have both agreed to return to GPL in case FDL makes problems. . (Note that this e-mail predates the current wording in LICENSES.) . It is therefore my understanding that the copyright holders of the groff documentation intend it to be distributable under the terms of the GPL version 3 or later.

License: LPPL-1.2+ The LaTeX Project Public License =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- . LPPL Version 1.2 1999-09-03 . Copyright 1999 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 license under which the base LaTeX distribution is distributed. . You may use this license for any program that you have written and wish to distribute. This license may be particularly suitable if your program is TeX-related (such as a LaTeX package), but you may use it even if your program is unrelated to TeX. The section `WHETHER AND HOW TO DISTRIBUTE PROGRAMS UNDER THIS LICENSE', below, gives instructions, examples, and recommendations for authors who are considering distributing their programs under this license. . In this license document, `The Program' refers to any program distributed under this license. . This license gives conditions under which The Program may be distributed and conditions under which modified versions of The Program may be distributed. Individual files of The Program may bear supplementary and/or superseding conditions on modification of themselves and on the distribution of modified versions of themselves, but *no* file of The Program may bear supplementary or superseding conditions on the distribution of an unmodified copy of the file. A distributor wishing to distribute a complete, unmodified copy of The Program therefore needs to check the conditions only in this license and nowhere else. . Activities other than distribution and/or modification of The Program are not covered by this license; they are outside its scope. In particular, the act of running The Program is not restricted. . We, the LaTeX3 Project, believe that the conditions below give you the freedom to make and distribute modified versions of The Program that conform with whatever technical specifications you wish while maintaining the availability, integrity, and reliability of The Program. If you do not see how to achieve your goal while meeting these conditions, then read the document `cfgguide.tex' in the base LaTeX distribution for suggestions. . . CONDITIONS ON DISTRIBUTION AND MODIFICATION =========================================== . You may distribute a complete, unmodified copy of The Program. Distribution of only part of The Program is not allowed. . You may not modify in any way a file of The Program that bears a legal notice forbidding modification of that file. . You may distribute a modified file of The Program if, and only if, the following eight conditions are met: . 1. You must meet any additional conditions borne by the file on the distribution of a modified version of the file as described below in the subsection `Additional Conditions on Individual Files of The Program'. . 2. If the file is a LaTeX software file, then you must meet any applicable additional conditions on the distribution of a modified version of the file that are described below in the subsection `Additional Conditions on LaTeX Software Files'. . 3. You must not distribute the modified file with the filename of the original file. . 4. In the modified file, you must acknowledge the authorship and name of the original file, and the name (if any) of the program which contains it. . 5. You must change any identification string in the file to indicate clearly that the modified file is not part of The Program. . 6. You must change any addresses in the modified file for the reporting of errors in the file or in The Program generally to ensure that reports for files no longer maintained by the original maintainers will be directed to the maintainers of the modified files. . 7. You must distribute the modified file under a license that forbids distribution both of the modified file and of any files derived from the modified file with the filename of the original file. . 8. You must do either (A) or (B): . (A) distribute a copy of The Program (that is, a complete, unmodified copy of The Program) together with the modified file; if your distribution of the modified file is made by offering access to copy the modified file from a designated place, then offering equivalent access to copy The Program from the same place meets this condition, even though third parties are not compelled to copy The Program along with the modified file; . (B) provide to those who receive the modified file information that is sufficient for them to obtain a copy of The Program; for example, you may provide a Uniform Resource Locator (URL) for a site that you expect will provide them with a copy of The Program free of charge (either the version from which your modification is derived, or perhaps a later version). . Note that in the above, `distribution' of a file means making the file available to others by any means. This includes, for instance, installing the file on any machine in such a way that the file is accessible by users other than yourself. `Modification' of a file means any procedure that produces a derivative file under any applicable law -- that is, a file containing the original file or a significant portion of it, either verbatim or with modifications and/or translated into another language. . Changing the name of a file (other than as necessitated by the file conventions of the target file systems) is considered to be a modification of the file. . The distribution conditions in this license do not have to be applied to files that have been modified in accordance with the above conditions. Note, however, that Condition 7. does apply to any such modified file. . The conditions above are not intended to prohibit, and hence do not apply to, the updating, by any method, of a file so that it becomes identical to the latest version of that file of The Program. . . . A Recommendation on Modification Without Distribution ----------------------------------------------------- . It is wise never to modify a file of The Program, even for your own personal use, without also meeting the above eight conditions for distributing the modified file. While you might intend that such modified files will never be distributed, often this will happen by accident -- you may forget that you have modified the file; or it may not occur to you when allowing others to access the modified file that you are thus distributing it and violating the conditions of this license. It is usually in your best interest to keep your copy of The Program identical with the public one. Many programs provide ways to control the behavior of that program without altering its licensed files. . . Additional Conditions on Individual Files of The Program -------------------------------------------------------- . An individual file of The Program may bear additional conditions that supplement and/or supersede the conditions in this license if, and only if, such additional conditions exclusively concern modification of the file or distribution of a modified version of the file. The conditions on individual files of The Program therefore may differ only with respect to the kind and extent of modification of those files that is allowed, and with respect to the distribution of modified versions of those files. . . Additional Conditions on LaTeX Software Files --------------------------------------------- . If a file of The Program is intended to be used with LaTeX (that is, if it is a LaTeX software file), then the following additional conditions, which supplement and/or supersede the conditions above, apply to the file according to its filename extension: . - You may not modify any file with filename extension `.ins' since these are installation files containing the legal notices that are placed in the files they generate. . - You may distribute modified versions of files with filename extension `.fd' (LaTeX font definition files) under the standard conditions of the LPPL as described above. You may also distribute such modified LaTeX font definition files with their original names provided that: (1) the only changes to the original files either enable use of available fonts or prevent attempts to access unavailable fonts; (2) you also distribute the original, unmodified files (TeX input paths can be used to control which set of LaTeX font definition files is actually used by TeX). . - You may distribute modified versions of files with filename extension `.cfg' (configuration files) with their original names. The Program may (and usually will) specify the range of commands that are allowed in a particular configuration file. . Because of portability and exchangeability issues in LaTeX software, The LaTeX3 Project deprecates the distribution of modified versions of components of LaTeX or of generally available contributed code for them, but such distribution can meet the conditions of this license. . . NO WARRANTY =========== . There is no warranty for The Program. Except when otherwise stated in writing, The Copyright Holder provides 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. . In no event unless agreed to in writing will The Copyright Holder, or any author named in the files of The Program, or any other party who may distribute and/or modify The Program as permitted above, be liable to you for damages, including any general, special, incidental or consequential damages arising out of any use of The Program or out of inability to use The Program (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 Program 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. . . WHETHER AND HOW TO DISTRIBUTE PROGRAMS UNDER THIS LICENSE ========================================================= . This section contains important instructions, examples, and recommendations for authors who are considering distributing their programs under this license. These authors are addressed as `you' in this section. . . Choosing This License or Another License ---------------------------------------- . If for any part of your program you want or need to use *distribution* conditions that differ from those in this license, then do not refer to this license anywhere in your program but instead distribute your program 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 program 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 program is unrelated to LaTeX, the discussion in `modguide.tex' may still be relevant, and authors intending to distribute their programs under any license are encouraged to read it. . . How to Use This License ----------------------- . To use this license, place in each of the files of your program both an explicit copyright notice including your name and the year and also a statement that the distribution and/or modification of the file is constrained by the conditions in this license. . Here is an example of such a notice and statement: . %% pig.dtx %% Copyright 2001 M. Y. Name % % This program may be distributed and/or modified under the % conditions of the LaTeX Project Public License, either version 1.2 % 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 1.2 or later is part of all distributions of LaTeX % version 1999/12/01 or later. % % This program consists of the files pig.dtx and pig.ins . Given such a notice and statement in a file, the conditions given in this license document would apply, with `The Program' referring to the two files `pig.dtx' and `pig.ins', and `The Copyright Holder' referring to the person `M. Y. Name'. . . Important Recommendations ------------------------- . Defining What Constitutes The Program . The LPPL requires that distributions of The Program contain all the files of The Program. It is therefore important that you provide a way for the licensee to determine which files constitute The Program. This could, for example, be achieved by explicitly listing all the files of The Program near the copyright notice of each file or by using a line like . % This program 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 Program. . Noting Exceptional Files . If The Program contains any files bearing additional conditions on modification, or on distribution of modified versions, of those files (other than those listed in `Additional Conditions on LaTeX Software Files'), then it is recommended that The Program contain a prominent file that defines the exceptional conditions, and either lists the exceptional files or defines one or more categories of exceptional files. . Files containing the text of a license (such as this file) are often examples of files bearing more restrictive conditions on modification. LaTeX configuration files (with filename extension `.cfg') are examples of files bearing less restrictive conditions on the distribution of a modified version of the file. The additional conditions on LaTeX software given above are examples of declaring a category of files bearing exceptional additional conditions. License: LPPL-1.3c+ 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 2008 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 % https://www.latex-project.org/lppl.txt % and version 1.3c or later is part of all distributions of LaTeX % version 2008 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.
