def require_version(required)
  # Gem::Version is intended for Ruby gem versions, but various web sites
  # suggest it as a convenient way of comparing version strings in
  # general.  None of the fine points of its semantics compared to those
  # of Git version numbers seem likely to cause a problem for Braid.
  Gem::Version.new(version) >= Gem::Version.new(required)
