|
|
Build a PKGBUILD on a remote server using makechrootpkg. Requires a remote user
|
|
that can run archbuild without password auth. Options passed after a -- are
|
|
passed on to archbuild, and eventually to makechrootpkg.
|
|
|
|
OPTIONS
|
|
-r, --repo Build against a specific repository (current: $repo)
|
|
-a, --arch Build against a specific architecture (current: $arch)
|
|
-s, --server Offload to a specific build server (current: $server)
|
|
-h, --help Show this help text
