Update to 0.55:

[Changes for 0.55 - 2006-07-29]

* ANDK submitted a patch to fix versioning problem when
  the user elects to install Crypt::OpenPGP.

* Major refactoring of the Makefile.PL to ease the installation process.

[Changes for 0.54 - 2006-05-12]

* Fixed a long-standing bug where differing end-of-line conventions
  could cause bogus comparisons in signature checks.

* Fixed another long-standing bug where CRLF text files were hashed
  into different digests under Unix and Dosish platforms.  Now it's
  consistently hashed as if it's been normalized to LF.

* Optional dependencies are no longer installed-by-default.

[Changes for 0.53 - 2006-01-31]

* The explicit call to "readline(D)" didn't compile on earlier perls which
  demanded either "readline(*D)" or "<D>" -- I elected \ 
the latter form.
  Reported by: Matthew Persic

* Update my author key to reflect revoked past uids.

[Changes for 0.52 - 2006-01-19]

* POD and source code cleanup; no functional changes.

* Updated my author key to reflect my new name and identity.

* Upgrade to the latest Module::Install to fix Cygwin
  installation problems.

[Changes for 0.51 - 2006-01-02]

* Even more flexible CRLF handling for SIGNATURE files,
  Contributed by: Andreas Koenig.

[Changes for 0.50 - 2005-08-21]

* Add support for to SHA-256, requested by Mark Shelor in light
  of the recent SHA1 attacks.  SHA1 is still the default, but
  you can now override this by settings MODULE_SIGNATURE_CIPHER
  environment variable to SHA256.

[Changes for 0.45 - 2005-08-09]

* Andreas Koenig ported out that "Import GPG keys?" was asked
  far too many times during autoinstall.
