# If your distro doesn't provide python-ctypeslib:
# svn co "https://svn.python.org/projects/ctypes/trunk/ctypeslib/"
# cd ctypeslib
# python2 ./setup.py install --prefix /tmp/out
# ln -s h2xml.py /tmp/out/bin/h2xml
# ln -s xml2py.py /tmp/out/bin/xml2py
# export PYTHONPATH="$PYTHONPATH:/tmp/out/lib/python2.7/site-packages"
# export PATH="$PATH:/tmp/out/bin/"
# ./regen-mncc-py.sh
# == Troubleshooting:
# * h2ml: Failing with tracebak OSError Not found:
#   One may be missing gccxml. On arch, install gccxml-git from AUR.
# * h2xml failing due to missing gccxml_builtins.h:
#   Create empty file /tmp/include/gccxml_builtins.h and pass "-I /tmp/include/" to h2xml.
# * Missing __builtin_bswap16/32/64:
#   Copy from /usr/include/bits/byteswap.h defines __bswap_constant_16/32/64 to
#   either start of mncc.h itself or /tmp/include/gccxml_builtins.h, and rename
#   them as __builtin_bswap16/32/64.
