Bundled gputils binaries — GNU General Public License v2 or later
-------------------------------------------------------------------------------

The platform wheels published to PyPI bundle a pre-built binary of the GNU PIC
Utilities assembler (gpasm) and its processor header files. These are NOT
covered by the MIT license above; they are distributed under the GNU General
Public License, version 2 or later (GPL-2.0-or-later).

Source:  https://sourceforge.net/projects/gputils/
         (built unmodified from gputils-1.5.2.tar.bz2; the build recipe is
         scripts/stage-gputils.sh in this repository)
License: https://www.gnu.org/licenses/old-licenses/gpl-2.0.html

Why this does NOT infect the rest of PyMCU
------------------------------------------
gputils is an *aggregated* work here, not a linked library: the PyMCU driver
invokes gpasm as a separate subprocess, which the GPL explicitly treats as
"mere aggregation". The GPL also places no restriction on the *output* of a
GPL program: firmware assembled by gpasm carries NO license obligation from
gputils. No part of the PyMCU compiler, standard library, or user firmware
inherits any condition from this package.

Corresponding source
--------------------
The exact, unmodified source archive for the bundled binaries is
gputils-1.5.2.tar.bz2 as published on SourceForge (SHA-256
8fb8820b31d7c1f7c776141ccb3c4f06f40af915da6374128d752d1eee3addf2), and is also
mirrored as an asset on this repository's GitHub Releases page.
