# 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 |
| 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. |
