sergiusens@lindon:~/source/launchpad.net/snapcraft/work$ ./bin/snapcraft help sources

A part that uses common source options can have these keyword entries:

    - source:
      (string)
      A path to some source tree to build. It can be either remote or local,
      and either a directory tree or a tarball.
    - source-type:
      (string)
      In some cases the source is not enough to identify the version control
      system or compression algorithim. This hints the system into what to
      do, the valid values are:

                   - bzr
                   - mercurial
                   - hg
                   - git
                   - tar

    - source-branch:
      (string)
      A specific branch from the source tree. This will result in an error
      if used with a bazaar source type.
    - source-tag:
      (string)
      A specific tag from the source tree.
