release command (see release):
$ cd .. $ cvs release -d tc M driver.c ? tc You have  altered files in this repository. Are you sure you want to release (and delete) directory `tc': n ** `release' aborted by user choice.
release command checks that all your modifications have been
committed. If history logging is enabled it also makes a note in the
history file. See history file.
When you use the ‘-d’ flag with

In the example above, the
release command wrote a couple of lines
of output. ‘? tc’ means that the file tc is unknown to CVS.
That is nothing to worry about: tc is the executable compiler,
and it should not be stored in the repository. See cvsignore,
for information about how to make that warning go away.
See release output, for a complete explanation of
all possible output from
‘M driver.c’ is more serious. It means that the file driver.c has been modified since it was checked out.
release command always finishes by telling
you how many modified files you have in your working
copy of the sources, and then asks you for confirmation
before deleting any files or making any note in the
