646 mk_exim_release [options] version PKG-DIRECTORY
647 mk_exim_release [options] --quick [version] PKG-DIRECTORY
651 B<mk_exim_release> builds an exim release.
653 Starting in a populated git repo that has already been tagged for
654 release it builds docs, packages etc. Parameter is the version number
655 to build as - ie 4.72 4.72-RC1, 4.86.1, etc, without any prefix.
657 This scripts expects to find a tag "exim-<version>".
659 After creating the release files, they should be signed. There is another
660 helper for creating the signatures:
661 F<release-process/scripts/sign_exim_packages>.
663 Call B<mk_exim_release> about like this:
665 release-process/scripts/mk_exim_release 4.99 OUT-DIR
672 =item B<--[no]cleanup>
674 Do (or do not) cleanup the tmp directory at exit (default: do cleanup)
676 =item B<--debug[=I<item>]>
678 Forces debug mode. If (default: no debug info)
682 =item item: B<version>
684 Output the parsed/found version number and exit.
688 =item B<--[no]delete>
690 Delete a pre-existing tmp- and package-directory at start. (default: don't delete)
694 Do (not) build the documentation. This needs C<gnu-make> (default: build the docs)
698 Display short help and exit cleanly. (default: don't do that)
700 =item B<--key> I<GPG key>
702 Use this GPG key for signing. If nothing is specified the first one of this list
707 =item - git config user.signingkey
709 =item - environment C<EXIM_KEY>
711 =item - default GPG key
717 Control the creation of B<lzip> tarballs. (default: do not use lzip)
719 =item B<--make-cmd> I<cmd>
721 Force the use of a specific C<make> command. This may be necessary if C<make> is not
722 C<gmake>. This is necessary to build the docs. (default: C<make>)
726 Display man page and exit cleanly. (default: don't do that)
730 Create a quick release. The I<version> mandatory argument needs to be a git commit-ish.
731 (try I<master> or I<HEAD> or similar). This mode switches off the
732 website creation (which can be enabled by B<--web> again).
736 Sign the created archive files (and the sizes.txt). (default: sign)
738 =item B<--tar-cmd> I<cmd>
740 Use to override the path to the C<tar> command. Need GNU tar in case
741 I<lzip> is selected. (default: C<gtar>, if not found, use C<tar>)
743 =item B<--tmpdir> I<dir>
745 Change the name of the tmp directory (default: temporary directory)
749 Force verbose mode. (default: no verbosity)
753 Control the creation of the website. For creation of the website, the F<../exim-website>
754 (but see the B<website-base> option) directory must exist. (default: create the website, except when
757 =item B<--website-base> I<dir>
759 Base directory for the web site generation (default: F<../exim-website>)
761 =item B<-workspace>|B<--tmp> I<directory>
763 During release gerneration temporary storage is necessary. (default: F<exim-packaging-XXXX>
764 under your system's default temporary directory (typically this is F</tmp>)).
