 493 CVS versions before 1.10 did not allow passing them arguments in different
 494 directories, so pcl-cvs checks what version you're using to determine
 495 whether to use the new feature or not.
 496 Sadly, even with a new cvs executable, if you connect to an older cvs server
 497 \(typically a cvs-1.9 on the server), the old restriction applies.  In such
 498 a case the sanity check made by pcl-cvs fails and you will have to manually
 499 set this variable to t (until the cvs server is upgraded).
 500 When the above problem occurs, pcl-cvs should (hopefully) catch cvs' error
 501 message and replace it with a message tell you to change this variable.")
