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