  Remstats was written by
  Thomas Erskine at the
  CRC in Canada and now
  at SourceWorks.

pattern-query  version 1.2 from remstats 1.0.13a
usage: ../pattern-query [options] pattern-file [file-to-search]
where options are:
  -h      show this help
  -m mmm  check 'mmm' matches at most [10]

This is for testing the infopattern and valuepattern regex's used in the port-collector scripts. Usually it's used in conjunction with the port-query program. The port-query program fetches data and the pattern-query program tests that data against various patterns.
