  *             PCRE testing program               *
  *************************************************/
+ /* This program was hacked up as a tester for PCRE. I really should have
+ written it more tidily in the first place. Will I ever learn? It has grown and
+ been extended and consequently is now rather, er, *very* untidy in places. The
+ addition of 16-bit support has made it even worse. :-(
