This is awesome!

Licensing question:  Is it that this specific implementation of gpr-tools doesn't make executables fall under the standard GPL license when used or is that true for all implementations (including the one from GNAT GPL from AdaCore that is used with the GPS IDE)?  I.E. can I use GPS, have it link to the AdaCore tools for gprbuild, but also link to the FSF GNAT instead of the AdaCore GNAT and be able to make products with the FSF style license?  Or does the fact that the tools come from AdaCore make them have a different affect on the license?

Realistically, I would still used the tools you are linking with the FSF version of GNAT, but was curious so I know what my options are.

Follow up would be can I then also just use the GPS IDE from AdaCore with the FSF GNAT and above mentioned tools you linked?  Or again, since GPS comes from AdaCore, I would still need to use a different IDE to avoid licensing issues.

My gut says the GPS IDE would be fine, but just my gut.
