  module Version #:nodoc:
    # A method for comparing versions of required modules. It expects two
    # arrays of integers as parameters, the first being the minimum version
    # required, and the second being the actual version available. It returns
    # true if the actual version is at least equal to the required version.

      actual   = actual.map { |v| "%06d" % v }.join(".")
      return actual >= required
