DFARS: http://www.acq.osd.mil/dp/dars/dfars/html/r20011001/252227.htm#252.227-7013 In the current DFARS, this appears to be subparagraph (b). Frankly the whole thing looks like a confusing mess but it appears to obligate the federal government to respect copyright law except in cases where software was developed exclusively with government funds. I recommend finding a lawyer. I really don't see anything in DFARS that would restrict the ability of the U.S. government to use any DFSG-free software, though it's possible DFARS may give them additional rights not granted by license (in which case you could argue that the restricted rights legend actually discriminates against non-government users) in certain cases, particularly if the entire project was government financed. I could only see this as a problem with something that was GPLed or otherwise copylefted (ex: GPLed software that is financed by the govt could be modified by the govt and combined with non-GPL-compatible software); a BSD-style license (which I think Tcl/Tk is under) doesn't restrict derived works anyway. If anything, it seems like a separate license for the government, which may or may not be the same thing as a discriminatory license... though we generally don't argue that dual-licensed software is non-free unless all of the licenses aren't DFSG-free and/or the range of all possible software users isn't covered by a DFSG-free license; e.g. GNU Ghostscript 6.51 is GPLed, but it was also licensed under the AFPL [as Aladdin Ghostscript 6.50] before being freed, and Aladdin licenses copies of Aladdin Ghostscript under other non-free licenses, yet GNU Ghostscript is DFSG-free. (I guess the question is: if I license software under a BSD-like license, but say in the license that people who use it to build nuclear power plants, have bad breath, or hang out with Osama bin Laden have to abide by the terms of the GPL with regards to the software, would that be non-free, even though both groups are covered by DFSG-free licenses?)
