    can tell you what version of a module is installed and what dependencies

    <para>The Module::Signature module is used to check and create

    tarball (if it includes a <filename>SIGNATURE</filename> file) by unpacking
    the tarball, changing into the newly created directory and issuing the
    command <command>cpansign -v</command>. It will check each file's
    integrity, as well as the signature's validity. Note that some of the
    dependencies appear to be circular, however, they are only run-time
    conflicts and you should be able to fully utilize them as long as
    everything is installed. Module::Signature and the dependency modules are

      This module implements the URI class. Objects of this class represent
      "Uniform Resource Identifier references" as specified in RFC 2396 (and
      updated by RFC 2732). A Uniform Resource Identifier is a compact string of
      characters that identifies an abstract or physical resource. A Uniform
      Resource Identifier can be further classified as either a Uniform Resource
      Locator (URL) or a Uniform Resource Name (URN). The distinction between
      URL and URN does not matter to the URI class interface. A "URI-reference"
      is a URI that may have additional information attached in the form of a
      fragment identifier. This module uses the standard
