Hello Matt,

I was notified by other as well that using the Mercurial Logo is also
subject to the GPL license.

After doing some read-up on the matter I decided to alter the license for
the full API (which uses the Mercurial logo) to GPLv2.

If I read the GPLv2 license, I understand that I don't need to use the GPL
license if I call the command line utility (without using the Logo in my
software). Is that correct?

Further information:
Since LabVIEW is a graphical language, the iconic representation of the
modules is part of the source-code. I created a palette with the functions I
created an API for,you can have a look at this here:
