=head1 NAME

mk_exim_release.pl - Build an exim release

=head1 SYNOPSIS

mk_exim_release.pl [options] version

 Options:
   --debug             force debug mode (SQL Trace)
   --verbose           force verbose mode
   --help              display this help and exits
   --man               displays man page
   --tar=cmd           command to use for tar
   --directory=dir     dir to package
   --no-lzip           do not create .tar.lz files
   --delete            Delete packaging directory at start

=head1 OPTIONS

=over 4

=item B<--debug>

Forces debug mode cause all SQL statements generated by L<DBIx::Class>
to be output.

=item B<--tar>

Use to override the path to the tar command; without this, will search for
gtar, and if not found use tar.  Need GNU tar for lzip, unless --no-lzip is
used.

=item B<--lzip>

Build the lzip tarballs.

=item B<--verbose>

Force verbose mode

=item B<--help>

Display help and exits

=item B<--man>

Display man page

=back

=head1 DESCRIPTION

Builds an exim release.

Starting in a populated git repo that has already been tagged for
release, build docs, build packages etc.

Parameter is the version number to build as - ie 4.72 4.72RC1 etc
