Re: embedded emc and GPL

[Paul <paul.corner-at-tesco.net>]

Hi Dean

I thought I'd leave this one for a few days to give the big guns to weigh in 
first - Surprised there hasn't been a response.

Below is a copy of Fred Procter's declaration on the subject when it cropped 
up in the summer of 2000. I would add that allthough this applies to EMC and 
the rcslib, Extensions such as Ray's Tcl/Tk routines, the modified Gnome 
stripchart, and the backplotter program are subject to GPL licenses.

For more information on this subject, might I suggest a read of the relevant 
FAQ in the handbook at www.linuxcnc.org .

Regards, Paul.

 Subject: EMC software copyright, etc. 

 EMC folks, 

 The EMC software was written by us U.S. government employees, and is  not 
subject to copyright. It's public domain. If we tried to keep it out of yourh 
ands we couldn't, because of the Freedom of Information Act. 
 You can do anything you want with it, like give it away, sell it, whatever. 
You can't copyright it yourself. 

 You can put an EMC on a machine tool and resell it, as some of you have 
done. This is great. You can make an easy-install CD and sell this for  big 
bucks, no problem. 

 We wrote this to support our work testing plug-and-play standards for  
machine tools and robots. There's no warrantee, support, or anything  like 
that. The emc-at-nist.gov mailing list is the support, and it's working great.
