0.21 (2009-07-03)
  - Added '--proxy' for check_jmx4perl and jmx4perl
  - check_jmx4perl:
    + Refactored to work within the embedded Nagios Perl interpreter
      (ePN)  
    + use relative values in the range from 0 to 100%
      (for --critical and --warning) instead of [0..1]
    + Renamed '--base-value' to '--base' since it can take now
      absolute values (numbers) or "mbean/alias/path" tuples as an
      argument in addition to alias names.
    + Added '--operation' which allows for using return values of
      operations as check values
    + Added ~ 50 integration tests
