module Jim

  # of the requirements in your Jimfile without having to rebundle using the command
  # line. You can specify a number of options:
  #
  # :jimfile: Path to your Jimfile (default ./Jimfile)
  # :jimhome: Path to your JIMHOME directory (default ENV['JIMHOME'] or ~/.jim)
  # :bundled_uri: URI to serve the bundled requirements
  # :compressed_uri: URI to serve the compressed requirements
