Restoring single file in project

[Michael Satterwhite]

First, I want to thank those who responded to my last query. I'm learning
CVS (coming from a Windows environment).

Assume for a moment that I have a project abc that I have just retrieved
from a CVS repository. After working for a while, I realize that I've been
going down a blind alley on one of the source files. Everything else I've
done is fine, but I need to get that one source file back.

How can I retrieve the latest copy of a single source file, overwriting the
(probably later) file in my work directory?

Thanks in advance for the help.
