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 -bFSF_DIST .
You must specify the -bFSF_DIST without any space after the -b. See admin options.
