# This script generates a template that can be used in the Python
# build process (on posix systems) in order to staticly link the
# wxPython modules into the Python executable.  The output of this
# script should be put into a file named Setup.local (or perhaps just
# concatenated to Setup) in the Modules dir of the Python source
# distribution, then just build Python like normal.
#
# You can use any of the command-line args that setup.py understands
# with this script too in order to control what modules are built and
# which compile options and such are used.
#
# This script must be run from the wxPython directory.
