Revision 502 - (show annotations)
Fri Mar 3 19:49:25 2006 UTC (15 years, 2 months ago) by michael
File MIME type: text/x-csrc
File size: 24852 byte(s)
- Implemented CAP command handler based uppon ircu's m_cap()
- Added somewhat outdated draft-mitchell-irc-capabilities-01.txt until
  I get the latest version from kev.
- Added "multi-prefix" cap so clients supporting "multi-prefix"
  may recieve multi prefixed NAMES replies, e.g. @%+nick1 @+nick2 ..
- Fixed "make clean" for src/conf/
