-/**
- * 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
