Nice idea!  There are two (minor) things I don't like.  First,
`binary' sounds misleading to me, as the contents actually are strings
rather than binary data.  I'd probably call it ID_TAG instead.

The second thing, @(#) and "what" are remnants of an old and now
completely obsolete revision control system named SCCS (source code
control system).  I've got Linux systems that don't have a what(1)
command at all.  These days, these lines would typically look like
$Id$ instead (corresponding to the ident(1) command).  For that
reason, I wouldn't want to hard-code the @(#) magic string but leave
the setup of the string entirely to the user.

Once an agreement has been reached in the discussion, please file that
as a patch tracker item so it won't get lost.  Please add a bit of
doxygen blurb.  Even if you can't test it, it helps speeding up the
patch integration later on (which I'm typically doing during release
preparations).
