 --- Info ---

 --- What is iroffer? ---

iroffer is a fileserver for irc (commonly referred to as a DCC bot).
It uses the DCC feature of irc to send files to other users. iroffer
will connect to an irc server and let people request files from it.
Unlike similar programs, iroffer is not a script, it is a standalone
executable written entirely in c from scratch with high transfer
speed and effeciency in mind.  iroffer has been able to sustain upto
50MByte/sec transfer rate over a gigabit ethernet link.

 --- Supported Platforms ---

Linux
FreeBSD, OpenBSD, BSD/OS, NetBSD
Solaris/SunOS

     screen and is cronable
