+/**
+ *  Written by MouseJstr in a vision... (2/21/2005)
+ *
+ *  This allows you to make npc listen for spoken text (global
+ *  messages) and pattern match against that spoken text using perl
+ *  regular expressions.
+ *
+ *  Please feel free to copy this code into your own personal ragnarok
+ *  servers or distributions but please leave my name.  Also, please
+ *  wait until I've put it into the main eA branch which means I
+ *  believe it is ready for distribution.
+ *
+ *  So, how do people use this?
+ *
+ *  The first and most important function is defpattern
+ *
+ *    defpattern 1, "[^:]+: (.*) loves (.*)", "label";
+ *
+ *  this defines a new pattern in set 1 using perl syntax 
+ *    (http://www.troubleshooters.com/codecorn/littperl/perlreg.htm)
+ *  and tells it to jump to the supplied label when the pattern
+ *  is matched.
+ *
+ *  each of the matched Groups will result in a variable being
+ *  set ($p1$ through $p9$  with $p0$ being the entire string)
+ *  before the script gets executed.
+ *
+ *    activatepset 1;
+ * 
+ *  This activates a set of patterns.. You can have many pattern
+ *  sets defined and many active all at once.  This feature allows
+ *  you to set up "conversations" and ever changing expectations of
+ *  the pattern matcher
+ *
+ *    deactivatepset 1;
+ *
+ *  turns off a pattern set;
+ *
+ *    deactivatepset -1;
+ *
+ *  turns off ALL pattern sets;
+ *
+ *    deletepset 1;
+ *
+ *  deletes a pset
