SCCS can retrieve any revision in one pass through the file. As you
say, there are the equivalent of "#ifdefs" that specify which revisions
include the following lines , so there's very little processing time,
it's mostly just I/O time. CVS as currently implemented has to read the
entire RCS file before doing anything, so I'd be very surprised if it's
significantly faster.
