+ * NEWS: updated
+ * README: updated (BeOS support, no longer shared libraries
+ support for AmigaOS), cleanups, we have now two mailing lists
+ * REAMDE-alpha: autogen -> bootstrap, we have now two mailing lists
+ * THANKS: added Xavier Pianet
+ * doc/PLATFORMS: BeOS works
+ * doc/libtool.texi: we have now to two mailing lists,
+ updated -dlopen self documentation, documented libltdl's license,
+ put each author in a separate line, cleanups and minor corrections
+ * libltdl/COPYING.LIB: new file
+ * libltdl/ltdl.[ch]: added special exception to the LGPL license
+ * libtool.spec: removed, it was outdated
+ * Makefile.am: removed libtool.spec
+ * ltmain.in: use TMPDIR when possible, create a subdirectory
+ in the temporary directory, added -export-symbols-regex to the help,
+ don't regenerate the .lai file if it was removed - it should not
+ happen
