   You do not remember modifying `driver.c', so you want to see what
has happened to that file.

     $ cd tc
     $ cvs diff driver.c

   This command runs `diff' to compare the version of `driver.c' that
you checked out with your working copy.  When you see the output you
remember that you added a command line option that enabled the
optimization pass.  You check it in, and release the module.

     $ cvs commit -m "Added an optimization pass" driver.c
     Checking in driver.c;
     /usr/local/cvsroot/tc/driver.c,v  <--  driver.c
     new revision: 1.2; previous revision: 1.1
     done
     $ cd ..
     $ cvs release -d tc
     ? tc
