Usage: $prog [options] [<namespace> <name>]

Build Anible Collection for ansible-freeipa.

The namespace defaults to freeipa an name defaults to ansible_freeipa,
if namespace and name are not given. Namespace and name need to be set
together.

Options:
  -a          Add all files, no only files known to git repo
  -k          Keep build directory
  -i          Install the generated collection
  -o <A.B.C>  Build offline without using git, using version A.B.C
              Also enables -a
  -p <path>   Installation the generated collection in the path, the
              ansible_collections sub directory will be created and will
              contain the collection: ansible_collections/<namespace>/<name>
              Also enables -i
  -h          Print this help
