It's a RCS/CVS tag. RCS and CVS are version control systems which help
to manage files in terms of timeseries; that is, you can refer to any
old state of a file even after you delete a part of it. See rcs(1),
pkgsrc/devel/cvs and its manuals.

There are many documents to recommend to use them, and *more* people
who can't manage to be used to them. ;-P
