update I've added three more lines, for dealing with additions, removals and messages about CVS itself.

Here, for your enjoyment and confusion is my .emacs file, which I use to customize my editing environment.

And here is a gem from my .bashrc, named for its ancestor, cvs update:

alias cup='cvs -q update -dP | perl -e "
while(<>){
  if(\$_=~/.*\.pyc\$/)          {;}
  elsif(\$_=~/^C\s\S.*/)        {print\"\033[1;31m\".\$_.\"\033[0m\";}
  elsif(\$_=~/^M\s\S.*/)        {print\"\033[1;33m\".\$_.\"\033[0m\";}
  elsif(\$_=~/^cvs\s\S.*/)      {print\"\033[1;34m\".\$_.\"\033[0m\";}
  elsif(\$_=~/^\?\s\S.*/)       {print\"\033[1;32m\".\$_.\"\033[0m\";}
  elsif(\$_=~/^A\s\S.*/)        {print\"\033[1;35m\".\$_.\"\033[0m\";}
  elsif(\$_=~/^R\s\S.*/)        {print\"\033[1;36m\".\$_.\"\033[0m\";}
  else{print\$_;}
}
";'

In a nutshell, it updates your folder from the source repository, removes deleted files and folders, and checks out newly-added ones. Also, the output is colored: green for files that you haven't added to the repository yet, yellow for merges, and red for conflicts. Everything else is in the normal grey color.
