Checking out specific revision

Hello, I'm relatively new to using the netbeans cvs module.  Hopefully this
is the correct place to ask questions.  I want to checkout a specific
revision of a file in order to do a diff.  Is there a standard way of doing
this, i.e. do you just check the file out into a temporary location and read
it?  Or is there a way to read the file's contents into memory using the
javacvs library without having to write to the filesystem?  Thanks.
