How to set path in Windows NT?

Tue May 15 19:55:26 EDT 2001

Not strictly Python related, but...

I've written a utility batch file that I'd like to be executable after
installing it on a computer.  How can I programmatically set the PATH
environment variable to include a directory of my choice, such that the next
time the user logs in or runs the command prompt, the variable will be set
accordingly?

Thanks.
