# Specify one action or more than one to provide a fall-back:
#
#   build     build the config files [the default w/no arg]
#   fetch     fetch the latest dev autoconfig files
#   fetchgen  fetch all the latest dev generated files (including manpages)
#   fetchSRC  fetch the latest dev source files [NON-GENERATED FILES]

# The script stops after the first successful action.
