How do I 're checkout' a file?

[remy . sharp]

Hi,

I'm fairly new to CVS but I have been trying to read around the subject
- so sorry in advance if this is a silly question.

I have checked out a file, made some changes but have decided I want to
revert back to the version in CVS.

One of my collegues suggested deleting the file, then doing a 'cvs
update' - I'm not convinced this is the best way of performing this
function.

Any suggestions?

Thanks in advance,

Remy.
