Default looking for Fermat factoring programs

Does anyone know of any good, user-friendly programs for trial-factoring large Fermat numbers, particularly those with m > 1000?

Leonid Durman's program is very user-friendly, but only goes up to around m = 1000. However, the other programs that were mentioned on the site either did not directly factor Fermat numbers, or were not user-friendly (or both).

So I'm looking for a program that can factor Fermat numbers with ease, and that won't cause me to look for the "readme" file every two minutes. It can be a command-line program, though.

Thanks in advance.
