CVS--Concurrent Versions System v18.104.22.168
13.3 Reverting to the latest vendor release
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'. See section A.6.1 admin options.
