= Packages in teTeX or TeXlive with problematic licenses =
This is a list of problematic files or CTAN packages in tetex-base and tetex-src, initially taken from tetex-base's copyright file (copyright.header in the source package).  Some things are not up-to-date - the extsizes stuff is already resolved, e.g.

== Serious problems ==
 * euler: LPPL according changelog, but no indication in file.
 * adrconv: No license at all for the documentation
 * antp: PD according to catalogue, no statement in the files, no
  . sources; contacted upstream
 * cite:  chapterbib.sty is missing a license statement in the header
 * bbm fonts: No license statement. The corresponding macros ''do'' have a license, LPPL
 * Problematic files by Donald Arseneau:
  * chapterbib.sty: no license information
  * tabls.sty: no license information
  * import.sty: "this software is free of any restrictions"
  * relsize.sty: "public domain", nothing else
  * version.sty: no license information, not only by D.A.
  * selectp.sty: no license information
 Files only in TeXLive:
  * braket.sty "This is free, unencumbered, unsupported software."
  * conditionals.sty: No license information, not only by D.A.
  * excludeonly.sty: No license information, not only by D.A.
  * notoccite.sty: PD, but license statement could be clearer
  * placeins.tex: No license information
  * sansmath: PD, but could be clearer (what is PD?)
  * tabto.tex: No license information
  * titleref.sty:  PD, spell out
  * underscore.sty: No license information
  * varwidth.sty: LPPL, but outdated "short version" included
 * citesort.sty: no license statement
 * extsizes: extsizes.sty, extarticle.cls and extreport.cls, and the
  . size*.clo files have a correct LPPL notice, the others have none. The author seems to be active on Wikipedia, tried to contact him
 * beamericon*: no license statement. beamerexample-seminar: just like
  . seminar, which has not been investigated yet.  Filed bug against beamer.
 * one file in the psnfss directory with unclear license:
  . tex/latex/psnfss/8r.sty
 * a4wide.sty: no license statement, obsolete, uses a4.sty, should be removed
 * jurabib: No license for the documentation,
== Less serious problems ==
 * listings: LPPL, plus:
  . ''''Modification advice''''
 Permission is granted to modify the listings package as well as lstdrvrs.dtx. You are not allowed to distribute a modified version of the listings package or lstdrvrs.dtx unless you change the file names and provide the original files. In any case it is better to contact the address below; other users will welcome removed bugs, new features, and additional programming languages.
This is more restrictive than LPPL 1.3 (6.a and 6.d.2). The title is advice...

 * antt: gust font license, unclear which files % contacted upstream
 * EC fonts: strange license wording, asked Karl Berry to contact Jörg Knappen, the author
 * anysize: public domain, no details (by TE)
 * aeguill: license of documentation unclear, sent mail to author
 * changebar.drv: Outdated file, unclear license, but probably the same as the new one which uses it; remove because it is obsolete.
