 The PURGE command allows you to delete obsolete versions of file from
 your directory.  Normally, the PURGE command deletes all but the most
 recent version of a file (by version number). 
2 KEEP
 The /KEEP qualifier allows you to specify that the last 'n' versions
 (by number) be saved. If you have three versions of a file numbered 1,
 2, and 3, /KEEP:2 will save the last two numerical versions (2 and 3)
 and delete version 1. However, if the versions were numbered 1, 2, and
 4, /KEEP:2 would try to save the last two numerical versions (3 and 4)
 and delete versions 1 and 2. Since version 3 did not originally exist,
 you would be left with only one version of the file in your directory.
 Normally this does not cause problems because you usually will not have
 holes in your directory like that.
