You can also revert local changes completely and return to the latest vendor release by changing the `head' revision back to the vendor branch on all files. For example, if you have a checked-out copy of the sources in ~/work.d/wdiff, and you want to revert to the vendor's version for all the files in that directory, you would type:

$ cd ~/work.d/wdiff
$ cvs admin -bWDIFF .

You must specify the -bWDIFF without any space after the -b. the section called “admin options”.
