Revision:	1.63
Committed:	Mon Apr 23 18:09:57 2007 UTC (17 years, 1 month ago) by root
Content type:	text/plain
Branch:	MAIN
Changes since 1.62:	+1 -1 lines
Log Message:	- add format utility function. - split dynbuf into dynbuf and dynbuf_text. - use dynbuf_text for examine strings instead of outputting each line seperately. tried to use stringstreams but they add insane overheads (as does std::string, but less so).
