Since we moved to Git from Subversion we've abandoned the ChangeLog file in favour of a more detailed commit log. In order to maintain a ChangeLog for users of the tarballs, we need to generate a ChangeLog file out of the commit log when distchecking a Clutter release. For this reason, we use a simple Perl script that is invoked by the dist-hook and generates a ChangeLog file starting from the previous stable release.

gen-changelog - Creates a ChangeLog from a git log
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
gen-changelog <options>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
B<gen-changelog> is a small Perl script that reads the output of git log
|
|
and creates a file using the GNU ChangeLog format. It should be used when
|
|
creating a tarball of a project, to provide a full log of the changes to
|
|
the users.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item -h, --help
|
|
|
|
Prints a brief help message
|
|
|
|
=item E<lt>sinceE<gt>..E<lt>untilE<gt>
|
|
|
|
Show only commits between the named two commits. When either E<lt>sinceE<gt>
|
|
or E<lt>untilE<gt> is omitted, it defaults to `HEAD`, i.e. the tip of the
|
|
current branch. For a more complete list of ways to spell E<lt>sinceE<gt>
|
|
and E<lt>untilE<gt>, see "SPECIFYING REVISIONS" section in git rev-parse.
