Thank you Massimo. Your script as is didn't work for me (I use debian

Can we have this feature in web2py? :-)

While he's very knowledgeable with web2py, I think John Heenan's

My understanding is this. The apps that you develop with Web2py does
not have to be GPL, and can be licensed in any way you want. (I am
unsure if this violates GPL's terms or not, but this is what I think
how web2py's licensing permits).
What is GPL is the web2py framework itself. So, as long
While I don't necessarily advocate for changing web2py's license, I
