title: How to have "cvs update" ignore some folders that CVS is managing?
body: <p>I have a system that uses CVS. Build takes a long time, partially because "CVS update" takes a long time. There are several folders that contain a lot of files that change rarely, if ever.
  I would like to have "CVS update" ignore those folders (i.e. not even look at them).
  I have tried .cvsignore and the -I options but they do not do what I want.</p>
  
  <p>Any suggestions?</p>
