+ * HACKING, README, README.alpha, TODO: Relax license to RMS
+ encouraged all-permissive terms.
+ * libltdl/README: Ditto. I added the original license text in
+ 2007, and there's no need for it to be so long for such a trivial
+ file.
+ * libltdl/config/getopt.m4sh, libltdl/general.m4sh: Cvs-utils is
+ dead, and I am the author of these files, so consolidated license
+ terms to match regular Libtool licensing.
+ * HACKING (Licensing Rules): Update wording, and list of files for
+ the all permissive license.
+ (GPL with CVS-Utils exception clause): Removed. No files have these
+ license any more.
+ (GPL with Libtool exception clause): Ditto, only libltdl/README
+ used to be distributed with this variation.
+ * AUTHORS: Add GPL license text.
+
Fix a type in the 2.2.8 release notes.
