+
+## Releasing
+
+1. bump the version in the Makefile
+2. Commit everything as  ```Version $(date +"%Y%m%d")```
+3. Create a new tag ```git tag -s $(date +"%Y%m%d")```
+4. Push changes
+5. Upload the source tarball with ```make dist upload```
+6. Update the package

+archbuild - a script to build an Arch Linux package inside a clean chroot.
+
+Synopsis
+--------
+archbuild [options] -- [makechrootpkg args]
+
+Description
+-----------
+
+'archbuild' is a script to build an Arch Linux package. archbuild is part of devtools but should only be used via one of the included symlinks:
+
+* extra-x86_64-build
+* gnome-unstable-x86_64-build
+* kde-unstable-x86_64-build
+* multilib-build
+* multilib-staging-build
+* multilib-testing-build
+* staging-x86_64-build
+* testing-x86_64-build
+
+The symlink used to run it will be inspected by archbuild, to determine which target you want it to use. It will load the available pacman configuration from 'pacman-reponame-arch.conf' with a fallback to 'pacman-reponame.conf' from {pkgdatadir}. The makepkg configuration is loaded from 'makepkg-repo-arch.conf' with a fallback to 'makepkg-reponame.conf' from {pkgdatadir}.
+
+
+Options
+-------
+
+*-h*::
+	Output command line options.
+
+*-c*::
+	Recreate the chroot before building.
+
+*-r* <dir>::
+	Create chroots in this directory.

+makerepropkg - Rebuild a package to see if it is reproducible
+
+Synopsis

+makerepropkg [OPTIONS] [<package_file|pkgname>...]
+
+Description
+-----------
+
+Given the path to a built pacman package(s), attempt to rebuild it using the
+PKGBUILD in the current directory. The package will be built in an environment
+as closely matching the environment of the initial package as possible, by
+building up a chroot to match the information exposed in the package's
+linkman:BUILDINFO[5] manifest. On success, the resulting package will be
+compared to the input package, and makerepropkg will report whether the
+artifacts are identical.
+
+When given multiple packages, additional package files are assumed to be split
+packages and will be treated as additional artifacts to compare during the
+verification step.
+
+A valid target(s) for pacman -S can be specified instead, and makerepropkg will
+download it to the cache if needed. This is mostly useful to specify which
+repository to retrieve from. If no positional arguments are specified, the
+targets will be sourced from the PKGBUILD.
+
+In either case, the package name will be converted to a filename from the
+cache, and makerepropkg will proceed as though this filename was initially
+specified.
+
+This implements a verifier for pacman/libalpm packages in accordance with the
+link:https://reproducible-builds.org/[Reproducible Builds] project.
+
+Options
+-------
+
+*-d*::
+	If packages are not reproducible, compare them using diffoscope.

+Description
+-----------
+
+Build a PKGBUILD on a remote server using makechrootpkg. Requires a remote user
+that can run archbuild in a non-interactive manner, e.g. must be able to
+elevate permissions using passwordless sudo.
+
+Options
+-------
+
+*-r, --repo* <reponame>::
+	Build against a specific repository. The default is `extra`, to build packages using
+	the stable repositories via extra-x86_64-build.
+
+*-a, --arch* <architecture>::
+	Build against a specific architecture. The default is `x86_64`, the only
+	architecture officially supported by Arch Linux.
+
+*-s, --server* <hostname>::
+	Offload to a specific build server. The default is build.archlinux.org
+	which is used as part of the build toolchain for the official Arch Linux
+	repos.
+
+*-h, --help*::
+	Show a help text.
+
+Passing options to archbuild
+----------------------------
+
+Options after a delimiting -- are passed on to archbuild on the remote.
+archbuild in turn supports passing arguments on to makechrootpkg, which in turn
+supports passing options to makepkg. Since each uses -- to delimit options that
+are forwarded, make sure to escape them properly:
+
+	`offload-build offload-args -- archbuild-args -- makechrootpkg-args -- makepkg-args`
+
+Example: To use a second `testing-x86_64-build` instance with another copydir:
+
+	`offload-build -r testing -- -- -l <chroot_copy>`
