release--Indicate that a Module is no longer in use
* release [-d] directories...
* Requires: Working directory.
* Changes: Working directory, history log.
This command is meant to safely cancel the effect of `cvs checkout'.
Since CVS doesn't lock files, it isn't strictly necessary to use this
command. You can always simply delete your working directory, if you
like; but you risk losing changes you may have forgotten, and you leave
no trace in the CVS history file (*note history file::) that you've
abandoned your checkout.
