# This shell script is used to fake Python. Gdb wants to be passed a
# Python interpreter, to run its own python-config.py program, which
# uses sysconfig. However, when cross-compiling, this doesn't work
# well since we would have to use the host Python, whose sysconfig
# module would return host values.
#
# As recommended at
# https://sourceware.org/gdb/wiki/CrossCompilingWithPythonSupport,
# this wrapper shell script can be used as a replacement. It ignores
# the python-config.py script passed as first arguments, and
# "emulates" its behavior.

# The first argument is the path to python-config.py, ignore it.
