The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

messy 130 column collage, output the system totals -or- info for a
specific interface if -I is given. Also wait for <interval> before
outputting the first sample so that it represents meaningful data (as
opposed to the total since the system was booted - most busy systems
wrap around many times during their operation, so these numbers are
only misleading).
