+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, with the extensions listed below.
+
+The latest version of the LaTeX Project Public License (without the
+extensions listed below) 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 Wolfgang Jeltsch.
+
+This work consists of all files found at
+
+ <http://darcs.wolfgang.jeltsch.info/tex/ucs/>
+
+including subdirectories.
+
+The following extensions to the LPPL apply for this work:
+
+ - A distribution may omit the files data/uninames.dat and
+ ucs-doc.dvi
+
+ - The directory structure may be changed
+
+ - A distribution may split the package into smaller packages, as
+ long as this fact is visible to the user and the user may easily
+ install the complete UCS package (e.g. by installing all small
+ packages).
+
+ - The data/uni-*.def files may be regenerated via makeunidef.pl from
+ a valid set of config/*.def files without changing the former's
+ names, whereby a valid set of config/*.ucf files consists of the
+ original files and any local additions in separate files, whereby
+ any characters defined in these should only be accessible via an
+ option which starts with the five letters 'local'. (See the
+ documentation files for a description of the technical terms and
+ names in this paragraph.)
+
+ - Files in the unsupported/ directory may be omitted.
+
+ - Scripts (i.e. executable files which are not TeX input), may be
+ renamed, as long as the original name without suffix is part of
+ the new name (e.g. discovermacro.pl -> latex-ucs-discovermacro)
+ and as long this is stated in some documentation file shipped with
+ the distribution. Occurrences of the scripts' names in the
+ documentation may be changed to match the new name.
+
+ - Parts of files explicitly marked as "configuration data" may be
+ changed by distributions, as long this is stated in a comment near
+ the place of that modification and in some documentation file
+ shipped with the distribution.
