# Name:    mx_config_win32_python
#
# Purpose: This script is used by the 'mx/tools/Makefile.win32' makefile
#          to construct a Windows batch file fragment that can be used
#          by the build scripts for other MX-related packages that use
#          the Python programming language.
#
# Warning: This script _must_ be run from the same directory that contains
#          the 'mx_config.exe' binary.
