Content type:	text/plain
Branch:	MAIN
Log Message:	initial import. the most important changes since Atheme are: - fixed many memory leaks - fixed many bugs - converted to C++ and use more STL containers - added a (not very enhanced yet) perl module - greatly improved XML-RPC speed - added a JSON-RPC module with code from json-cpp - added a valgrind memcheck module to operserv - added a more object oriented base64 implementation - added a specialised unit test framework - improved stability - use gettimeofday() if available - reworked adding/removing commands - MemoServ IGNORE DEL can now remove indices
