xypcre is a collection of user-defined functions that provides PCRE support to XYplorer scripts.
PCRE is an advanced form of Regular Expressions that allows for many advanced regexp operations not supported by XYplorer's built-in regexp engine.
xypcre functions allow XYplorer to use an advanced Regular Expression engine instead of the limited
VB implementation of regexmatches() and regereplace(). This is achieved by offloading regexp operations
to a helper utility, xypcre.exe (currently written in AutoIt3).
