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

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
