#	PostProcessor.pm
#	=================
#
#	This is called by "post_process.MgOpenSource.pl".
#
#	Purpose:
#		Does some post-processing of the HTML files produced
#		by Doxygen, to fix things that we cannot configure
#	    through Doxygen.
#
#		1) Removes the "File List", "File Members", and "Namespaces" nodes from the Table Of Contents.
#		2) Removes '__get', '__set', and '__inherit'. (These are SWIG commands
#		   but because they are in the comments they get picked up by Doxygen.)
#		3) Sets the title to be shown in the web browser.
#		4) Fixes the links in the top-of-page tabs on the first page (index.htm)
#		   the user sees.
#		   (If you have DISABLE_INDEX set to NO, the default, in the Doxygen
# 		    configuration file, then Doxygen puts tabs at the top of each page,
#			with links to "Main Page, "Modules", etc.  We don't want to show
#  		    the "Files" or "Namespaces" tab, so we set DISABLE_INDEX to YES, and add the desired tabs
#		    to our custom header (which we specify via HTML_HEADER).
#			We also have CREATE_SUBDIRS set to YES, so some pages are in
#			subdirectories, and some are at the root level.  The links in
#			our custom header are fine for pages in subdirectories, but need
#			to be fixed for pages in the root level.  (EG, index.htm.)
#		5) Changes the default name of the top node in the Table Of Contents,
#		   "Root", to something more informative.
#		6) Makes similar changes in the index.hhc and index.hhp files.  (These
#	       will be present if we are compiling the help into a .CHM.)
#
#	History:
# 		v 1.0 	- Written by Philip Sharman, 2008.02.12
# 		v 1.1 	- Now uses Find::Bin to determine the script's location.  
#				- Also uses File::Spec-&gt;canonpath to clean up any mixture of
#				  slashes and backslashes in file paths. 
#				- Moved the main part ('do_it') to here instead of in the calling script.
#				  PHS, 2008.02.14
#		v 1.2	- Changed to not use any external Perl modules, to make it easier to
#				  distribute.  PHS, 2008.02.20
#		v 1.3	- Added 'change_root()', 'remove_namespace()', 'remove_namespace_from_HHC()' etc.  
#                 PHS, 2008.02.24
