#  Temporary hack of a script to get FreeBSD user space header
#  files and network libc source code into this tree.
#
#  NOTE: libc and include are NOT in the FreeBSD checkout used for the
#        USB and TCP/IP stacks. This has to be addressed.
#
#  This probably could be integrated into the main Python script.
#  But so far, there are no real transformations needed and the
#  script just performs two tasks:
#
#  + copies source files from FreeBSD libc and include files into this tree
#  + generates "wrapper" header files for the public network .h files
