/******************************************************************************
* $Id$
*
* Project: MapServer
* Purpose: Functions to allow copying/cloning of maps
* Author: Sean Gillies, sgillies@frii.com
*
* Notes:
* These functions are not in mapfile.c because that file is
* cumbersome enough as it is. There is agreement that this code and
* that in mapfile.c should eventually be split up by object into
* mapobj.c, layerobj.c, etc. Or something like that.
*
* Unit tests are written in Python using PyUnit and are in
* mapscript/python/tests/testCopyMap.py. The tests can be
* executed from the python directory as
*
* python2 tests/testCopyMap.py
*
* I just find Python to be very handy for unit testing, that's all.
