Re: Runtime versions (GPL vs Modified GPL)

[anon@anon.org (anon)]

First, the orginal poster does not want to use the GPL.

And the GNAT GPL is under the GPL.

As publish in the spring of 2007, the GNAT PRO was $14_000 per 
year.

The "special exception" clause allows the programmer to use GNAT 
acadamic or GPL to develope the software under a compatable GPL
license or the LGPL which is still apart of the GPL license structure.
Or they can develope the software using GNAT and then use GNAT PRO, 
Green hil, etc. Ada to compile the release binary version under another 
license.
