Hopefully provide output from ascend-config that is acceptable to SCons 1.3.x and newer.

6     # This file is generated automatically by SCons and installed in at INSTALL_BIN.
7     # Use it to query for local configuration of ASCEND on your system for example
8     # when building external 'plugins' such as external computations and external
9     # solvers etc.
10     #
11     # It's written in python since (because of SCons) we know we have Python on
12 johnpye 692 # this system already but we don't know that about unix shell (eg on Windows).
13 johnpye 683 #
14     # Note that SCons supports reading of the output from this script, using
15 johnpye 965 # features offered since version 0.96.91, although this functionality
16     # is a bit problematic on the Windows platform, and/or when paths contain spaces.
17 johnpye 683 #
18     # This file inspired by other software that uses the same approach, eg
19     # ginac-config, xft-config, cppunit-config.
20     #
21     # Type ascend-config --help for usage.
