Usage: ${COMMAND} [OPTIONS] [PATH]...
Build packages inside a clean chroot
When a new pkgver is set using the appropriate PKGBUILD options the
checksums are automatically updated.
TODO
BUILD OPTIONS
--arch ARCH Specify architectures to build for (disables auto-detection)
--repo REPO Specify a target repository (disables auto-detection)
-s, --staging Build against the staging counterpart of the auto-detected repo
-t, --testing Build against the testing counterpart of the auto-detected repo
-o, --offload Build on a remote server and transfer artifacts afterwards
-c, --clean Recreate the chroot before building
-I, --install FILE Install a package into the working copy of the chroot
--inspect WHEN Spawn an interactive shell to inspect the chroot (never, always, failure)
-w, --worker SLOT Name of the worker slot, useful for concurrent builds (disables automatic names)
--nocheck Do not run the check() function in the PKGBUILD
PKGBUILD OPTIONS
--pkgver=PKGVER Set pkgver, reset pkgrel and update checksums
--pkgrel=PKGREL Set pkgrel to a given value
--rebuild Increment the current pkgrel variable
--update-checksums Force computation and update of the checksums (disables auto-detection)
-e, --edit Edit the PKGBUILD before building
RELEASE OPTIONS
-r, --release Automatically commit, tag and release after building
-m, --message MSG Use the given <msg> as the commit message
-u, --db-update Automatically update the pacman database as last action
OPTIONS
-h, --help Show this help text
EXAMPLES
$ ${COMMAND}
$ ${COMMAND} --rebuild --staging --message 'libyay 0.42 rebuild' libfoo libbar
$ ${COMMAND} --pkgver 1.42 --release --db-update
