Folks, See below the Latex License.
http://www.latex-project.org/lppl.html It seems to me that clause '8.B" makes this license more restrictive than the ASF license - and we thus should not allow code(fragements) which are under this license in downloads from ASF infrastructure. Or am I misreading things - the license is long and weildy. Dw LaTeX Project Public License LPPL Version 1.2 1999-09-03 Copyright 1999 LaTeX 3 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 LaTeX 3 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: 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'. 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'. You must not distribute the modified file with the filename of the original file. 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. You must change any identification string in the file to indicate clearly that the modified file is not part of The Program. 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. 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. 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 ofs) with their eX 3 Project deprecates the distribution of modified versions of components of LaTeX or of generally available contributed code for them, but such distributioogram.

The entire risk as to the quality and per party who may distribute and/or m ut of inability to use The Program (including, but not limited to, loss of data, data being relure of The Program to operate with any other program, even if The Copyright Holder or said author or said other party has been advised of the possibility of such dasection contains important instructions, examples, and recommendations for authors who athors are addressed as `you' i 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.
