Hello Roger,

this is very easy:
At the moment where a author published a software which based on GPL parts(!!),
parts are enought (example using Fruit move generator), they must allso be
publishing the source code. This includes allso version send via mail to private
person, here are some testers.

Its not importent if its a testversion or not.

A public download place must allso offer the source (a link is enought of
course).
