Version 0.5.1 / Fri, Sept 7 2007
  - Improved conformance to squirrelmail plugin coding guidelines.
  - Added automatic setting of From header in vacation file using the
    From address defined in the squirrelmail prefs.
    Thanks to Tomasz Witek for the patch.
  - Added Japanese translation, but having trouble getting it working.
    Thanks to Yasuhiro Suzuki for the translation.
  - Removed use of the compatibility plugin.  I'm told that the use of
    sqgetGlobalVar means this plugin will only work with squirrelmail 1.4
    and newer.  If anybody wants the compatibility plugin integrated
    back in, please let me know.

Version 0.5 / Wed, Sept 5 2007
  - Added internationalization and Italian translation.  Thanks to
    Gabriele Vivinetto for the suggestion, translation, and head start.
  - Added ability to pass alternate alias names to the vacation program
    at the request of a few people.
  - Added ability to wipe out the vacation reply cache at the request
    of a few people.
  - Added keep_by_default config option.  Thanks for Daniel Watts for
    the suggestion.
    

Version 0.4 / Fri, Jun 27 2003
  - Fixed a bug where a user couldn't leave on filtering if they weren't
    doing a forward or vacation response.
  - Added more comments to config.php, converted the examples from
    a qmail setup to postfix/sendmail.
  - Tried to avoid creating some unnecessary PHP log warnings.
