676 mk_exim_release [options] version PKG-DIRECTORY

681 B<mk_exim_release> builds an exim release.
683 Starting in a populated git repo that has already been tagged for
684 release it builds docs, packages etc. Parameter is the version number
685 to build as - ie 4.72 4.72-RC1, 4.86.1, etc, without any prefix.
687 This scripts expects to find a tag "exim-<version>".
689 After creating the release files, they should be signed. There is another
690 helper for creating the signatures:
691 F<release-process/scripts/sign_exim_packages>.
693 Call B<mk_exim_release> about like this:
695 release-process/scripts/mk_exim_release 4.99 OUT-DIR
702 =item B<--[no]cleanup>
704 Do (or do not) cleanup the tmp directory at exit (default: do cleanup)
706 =item B<--compressors> [I<action>]I<compressor[I<action>$<compressor>]...
708 A list of compressors to use. Currently the default list is
709 B<gzip>, B<xz>, and B<bzip2>, with B<lzip> optionally to be enabled.
711 I<action> can be "+" (add), "-" (remove), and "=" (set).
713 =item B<--debug[=I<item>]>
715 Forces debug mode. If (default: no debug info)
719 =item item: B<version>
721 Output the parsed/found version number and exit.
725 =item B<--[no]delete>
727 Delete a pre-existing tmp- and package-directory at start. (default: don't delete)
731 Do (not) build the documentation. This needs C<gnu-make> (default: build the docs)
735 Display short help and exit cleanly. (default: don't do that)
737 =item B<--key> I<GPG key>
739 Use this GPG key for signing. If nothing is specified the first one of this list
744 =item - git config user.signingkey
746 =item - environment C<EXIM_KEY>
748 =item - default GPG key
752 =item B<--make-cmd> I<cmd>
754 Force the use of a specific C<make> command. This may be necessary if C<make> is not
755 C<gmake>. This is necessary to build the docs. (default: C<make>)
759 Display man page and exit cleanly. (default: don't do that)
763 Create a quick release. The I<version> mandatory argument needs to be a git commit-ish.
764 (try I<master> or I<HEAD> or similar). This mode switches off the
765 website creation (which can be enabled by B<--web> again).
769 Sign the created archive files (and the sizes.txt). (default: sign)
773 Write the sizes information to F<sizes.txt>. (default: write sizes)
775 =item B<--tar-cmd> I<cmd>
777 Use to override the path to the C<tar> command. Need GNU tar in case
778 I<lzip> is selected. (default: C<gtar>, if not found, use C<tar>).
780 =item B<--tmpdir> I<dir>
782 Change the name of the tmp directory (default: temporary directory)
786 Force verbose mode. (default: no verbosity)
790 Control the creation of the website. For creation of the website, the F<../exim-website>
791 (but see the B<website-base> option) directory must exist. (default: create the website, except when
794 =item B<--website-base> I<dir>
796 Base directory for the web site generation (default: F<../exim-website>)
798 =item B<-workspace>|B<--tmp> I<directory>
800 During release gerneration temporary storage is necessary. (default: F<exim-packaging-XXXX>
801 under your system's default temporary directory (typically this is F</tmp>)).
