    description <<-EOT
      Prepares a local module for release on the Puppet Forge by building a
      ready-to-upload archive file.
      Note: Module build uses MD5 checksums, which are prohibited on FIPS enabled systems.

      This action uses the metadata.json file in the module directory to set metadata
      used by the Forge. See <https://puppet.com/docs/puppet/latest/modules_publishing.html> for more
      about writing metadata.json files.

      After being built, the release archive file can be found in the module's
      `pkg` directory.
    EOT

    returns _("Pathname object representing the path to the release archive.")
