_//_ _\_ The ``Eiffel Tower'' Release
* autoupdate.sh: Complete rewrite. See that file for a detailed
explanation. Basically, simulate the name spaces thanks to
`autoconf --trace' and auxiliary files.
No longer use `autoupdate.m4', remove the dependencies.
Synchronize the options and `--help'.
* doc/autoconf.texi (Invoking autoupdate): Humanoupdate.
* autoupdate.m4: Delete.
* tests/Makefile.am (FILTER_MACROS): Add `AC_OUTPUT'.
Since `AC_OUTPUT' is now AU_DEFUN'd, it is extracted for testing,
while it was not before.
* tests/tools.m4 (autoupdate): Re-enable. Adjust the expected
output with the right quotation (yeah!).
Pass `-m $top_srcdir': autoupdate want the `.m4' files, not the
frozen files.
* Makefile.am (nodistpkgdataDATA): Move `acversion.m4' to
(distpkgdataDATA): here, so that all the `.m4' files are in the
source hierarchy, not split across src and build.
* acversion.m4.in: Update to today's standards.
* Makefile.am: Adjust.
