            Re: Is this really "freeware" or "free to use but restricted"
            I looked pretty closely at the license definitions before setting the license type, but now I can't find the definitions anymore so it's hard to argue about it. NAMD is not free to distribute. It's free to use but you can't sell it. Read the license.
