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