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

5 #---------------------
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 # this system already but we don't know that about unix shell (eg on Windows).
13 #
14 # Note that SCons supports reading of the output from this script, using
15 # 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 #
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.
