/*
 * The architecture of this extension is relatively complex. The main Perl
 * class is P4 which is a blessed scalar containing pointers to our C++ 
 * objects which hold all our real data. We try to expose as little as
 * possible of the internals to Perl.
 *
 * As the Perforce API is callback based, we have some tap-dancing to do
 * in order to shim it into Perl space. There are two main C++ classes:
 *
 * 1  PerlClientUser is our subclass of the Perforce ClientUser class. This 
 *    class handles all the user-interface functions needed in the API - i.e.
 *    getting input, writing output/errors etc.
 *
 * 2. PerlClientApi is our interface to the Perforce ClientApi class. It
 *    provides a type-bridge between Perl and C++ and makes sure
 *    that the results it returns are ready for use in Perl space.
 *
 * This module provides the glue between Perl space and C++ space by
 * providing Perl methods that call the C++ methods and return the appropriate
 * results.
