Committed:	Sat Feb 11 23:14:21 2006 UTC (20 years, 6 months ago) by adx
Content type:	text/x-csrc
File size:	4555 byte(s)
Log Message:	+ massive rewrite of module init/deinit/version headers, we are introducing a new module manager which deals with static and dynamic modules exactly the same way. (New possibilities include loading/unloading statically compiled modules and mixing static/dynamic ones in one build.)
