# This file is generated automatically by SCons and installed in at INSTALL_BIN.
# Use it to query for local configuration of ASCEND on your system for example
# when building external 'plugins' such as external computations and external
# solvers etc.
#
# It's written in python since (because of SCons) we know we have Python on 
# this system already but we don't know that about unix shell (eg on Windows).
#
# Note that SCons supports reading of the output from this script, using
# features offered since version 0.96.91, although this functionality
# is a bit problematic on the Windows platform, and/or when paths contain spaces.
#
# This file inspired by other software that uses the same approach, eg
# ginac-config, xft-config, cppunit-config.
#
# Type ascend-config --help for usage.
