libtool/libtoolize.in
Gary V. Vaughan 9a7495a24d * config/mkstamp: Change output format to ` $rev $date'.
* configure.ac: Make the banner more like suggestions in
http://www.gnu.org/prep/standards_toc.html Section 4.6.
* libtoolize.in: Make --version output conform to the GNU
standard.
* ltmain.in: Ditto. And tweak the generated file headers to
match.
