macwatch is a small daemon that counts in- and
outbytes from a given MAC-address and stores the
result in a file for use with MRTG. It will write
the file every 5 minutes by default, and uses
libpcap to do all the work.

A minor bug introduced by a previous bugfix was
fixed. The mac-address check now allows addresses
to be specified as dash-delimited numbers instead
of colon-delimited numbers.
