Usage: $(basename $0) < save [ -d ] | fetch [ -v <view> ] | purge >

Commands:
  save          -- Stash modified files under ${HOME}/src/.
  fetch         -- Sync files from ${HOME}/src/<view> to /usr/src/.
  purge         -- Remove stashed files.

Options:
  -d            -- Only stash modified files under the current directory.
  -v view       -- Specify the view to fetch files from. An attempt to guess
                   will be made if the view isn't specified.
