Once the checkout command completes, you'll see a "samba" directory in your current working directory that contains the latest sources. You'll also notice that all the directories have a "CVS" directory inside them -- CVS stores accounting information inside these directories, and they can safely be ignored. From this point forward, we don't need to worry about having the CVSROOT environment variable set nor do we need to specify it on the command line because it's now cached inside all those extra "CVS" directories. Remember -- you only need to have the CVSROOT set for the initial login and checkout.
