This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU Autoconf source repository".

commit 2d4eb959325a8c7af0c03c9ed580c563b04d77cb
Author: Eric Blake <address@hidden>
Date: Tue Apr 24 21:06:32 2012 -0600
maint: post-release administrivia
* NEWS: Add header line for next release.
* .prev-version: Record previous version.
* cfg.mk (old_NEWS_hash): Auto-update.
commit 771017a4336bcc38b99c84e345c94a8910b89996
Author: Eric Blake <address@hidden>
Date: Tue Apr 24 20:17:06 2012 -0600
Release Version 2.69.
* NEWS: Mention the release.
Signed-off-by: Eric Blake <address@hidden>
commit 19513cca18398fb43c953031e6da63252fe7f8f2
Author: Eric Blake <address@hidden>
Date: Tue Apr 24 20:38:57 2012 -0600
maint: drop bz2 tarball
At 2.68b, I asked whether anyone would miss .gz and .bz2 formats.
Consensus was overwhelming that .gz still holds a place in people's
hearts, in spite of .xz compressing to smaller files, but no one
was able to make a convincing argument for .bz2.
* configure.ac (AM_INIT_AUTOMAKE): Drop bzip2; xz wins hands down.
Signed-off-by: Eric Blake <address@hidden>
commit 84e20e9164b7e7ccc189eb68c5f839ec28d276ae
Author: Eric Blake <address@hidden>
Date: Tue Apr 24 17:30:37 2012 -0600
maint: resync files from upstream
The files in lib/Autom4te/ are intentionally not synced at this
point, since this recent Automake patch:
https://lists.gnu.org/archive/html/automake-patches/2012-03/msg00111.html
was buggy regarding '-' as stdout, and also exposes some latent
bugs in autoconf where we use raw 'open' instead of XFile::open.
* build-aux/announce-gen: Resync via 'make fetch'.
* build-aux/config.sub: Likewise.
* build-aux/git-version-gen: Likewise.
* build-aux/gnupload: Likewise.
* build-aux/move-if-change: Likewise.
* build-aux/texinfo.tex: Likewise.
* doc/standards.texi: Likewise.
* maint.mk: Likewise.
commit f35498d15cd291a476594ed1b12b8d198310efb0
Author: Eric Blake <address@hidden>
Date: Tue Apr 24 20:08:06 2012 -0600
doc: fix bad @xref uses
Upstream gnulib maint.mk improvements caught a few issues we
should fix, as well as a few issues in files we copy from
other sources that we will just ignore here.
* doc/autoconf.texi (Generic Programs, Special Shell Variables)
(Limitations of Builtins): Use references correctly.
* cfg.mk
(exclude_file_name_regexp--sc_prohibit_undesirable_word_seq)
(exclude_file_name_regexp--sc_useless_cpp_parens): Add exemptions.
