-Most of the configure-related files are automatically generated. The only files
-you should need to manually edit are acconfig.h and configure.in. Don't, for

+If you wish to change the `configure' script, the generated Makefile
+or other related files, you'll need to first install GNU m4, available
+from , then GNU autoconf
+() and GNU automake
+(). Nmh is currently using a
+minimum of autoconf 2.61 and automake 1.10.
-If you do change acconfig.h or configure.in and want to `cvs commit' them, be
-sure to regenerate the output files and commit them as well. The easiest way to
-regenerate the files is to simply run `make' -- it'll do the necessary calls of
-autoconf and autoheader and will do a `./config.status --recheck', which will

+Most of the configure-related files are automatically generated.
+The only files you should need to manually edit are configure.ac
+and any autoconf macros in the m4 directory. Don't, for instance,
+edit config.h.in. Though it is an input file from the point of
+view of the users (and the configure script) it is an output file
+from the point of view of the developers (and the autoconf script).
-When you commit the configure-related files, it's very important to commit them
-in the right order. The timestamps on the files in the CVS archive are based on
-the current time at the moment they were committed -- the timestamps from the
-local files you commit are not copied over. If you commit the files in the
-wrong order, you'll cause unnecessary calls of `autoconf' to occur when people
-try to `make' their copies of the latest CVS source. These people may be
-end-users who don't have any interest in changing the configure-related files
-and don't have autoconf installed. They'll be unable to make without playing
-around with `touch'.
+If you wish to add a new autoconf macro, it should be placed in it's
+own file and put in the m4 directory; aclocal will automatically pick
+it up and automake will add it to the distribution target automatically.
-The correct order to commit the configure-related files is:
+If you wish to make changes to the Makefile, you will need to edit
+Makefile.am. See the automake documentation if you need further help.
+You should always check changes to Makefile.am by using "make distcheck".
-% cvs commit acconfig.h aclocal.m4 config.h.in configure.in configure stamp-h.in
+Note that the automatically generated autotools files (such as config.h.in,
+Makefile.in, and configure), are NOT kept in git. Thus, when you check out
+a git tree, you need to run the autogen.sh script before you can build
+anything:
-If you haven't changed all of those files, just commit the rest in the

+To make a public release of nmh (we'll use version 1.5 as the example
+here; the convention for release candidates is to use something like
+"1.5-RC1"):
+
+ 1. % echo 1.5 > VERSION
+ % date +"%e %B %Y" > DATE
+ (DATE should contain something like "30 December 2000")
+
+ 2. % git commit VERSION DATE; git push
+
+ 3. % git tag -a 1.5 -m 'Releasing nmh-1.5.'
+
+ Note that the new convention for tagging is to simply tag with the
+ version number (tag formats in the past have varied).
+
+ 4. % make distcheck
+
+ If you want to check the distribution build with some particular
+ configure options, set the DISTCHECK_CONFIGURE_FLAGS variable.
+ E.g.:
+
+ % make distcheck DISTCHECK_CONFIGURE_FLAGS=--with-cyrus-sasl
+
+ 5. If all is well and your tarball is final, go back to your workspace and do:
-1. % echo 1.0.4 > VERSION
+ % echo 1.5+dev > VERSION
-2. Put a comment like "Released nmh-1.0.4." in the ChangeLog.
+ 6. % git commit VERSION; git push
-3. % cvs commit ChangeLog VERSION
+ 7. Upload the distribution file to savannah. You can automate this process
+ by doing:
-4. % cvs tag nmh-1_0_4
- (cvs treats dots specially, so underscores are substituted here.)
+ % make upload SAVANNAH_USERNAME=username
-5. % make nmhdist
+ This will automatically call gpg to sign the release. You can bypass
+ this step by setting the SKIP_GPG_SIG variable.
-6. Preferably make an MD5 hash and/or a PGP signature of nmh-1.0.4.tar.gz.
+ 8. Update the http://www.nongnu.org/nmh/ homepage. (It lives in the CVS
+ 'webpages repository'; see https://savannah.nongnu.org/cvs/?group=nmh)
-7. Preferably test out the tarball, making sure you can uncompress and untar it,
- and configure, make, install, and use nmh from it.
+ 9. Add a news item to the savannah nmh page. You'll have to submit it first
+ and then separately approve it (under News->Manage).
-8. % scp -p nmh-1.0.4.tar.gz* your-uid@mhost.com:/home/ftp/pub/nmh
+10. Send the release announcement email to the following places:
+ nmh-workers@nongnu.org
+ nmh-announce@nongnu.org
+ exmh-users@redhat.com
+ exmh-workers@redhat.com
+ mh-e-users@lists.sourceforge.net

- bugtraq@securityfocus.com. The exmh lists require you to be subscribed in
- order to post. Note that you don't need to post separately to comp.mail.mh,
- as the mh-users mailing list is apparently bidirectionally gatewayed to it.
