Question about CVS

[Cheng Ie-Sun]

Got 2 questions regarding CVS 1. Is it possible to limit the number of revisions that CVS creates?     ie. 5 revisions, 1.1x, 1.2x, 1.3x, 1.4x and 1.5x 2. Is it possible to remove the old revisions     ie. remove revisions 1 tru 49 and just leave revision 50 and 51 from a 51 revision file   Appreciate your help. Thanks
