Help("""
Usage: scons [OPTIONS] [TARGET] [CONFIG]
[OPTIONS] and [TARGET] are covered in command line options, use scons -H
[CONFIG]: KEY="VALUE" [...]
a number of configuration options saved between runs in the """ + conf_filename + """ file
erase """ + conf_filename + """ to start with default settings again
CC
CXX
Specify C and C++ compilers (defaults gcc and g++)
ex: CC="gcc-3.2"
You can use ccache and distcc, for instance:
CC="ccache distcc gcc" CXX="ccache distcc g++"
JOBS
Parallel build
ex: JOBS="4" is a good setting on SMP machines
BUILD
Use debug/release to select build settings
ex: BUILD="release" - default is debug
