SCons build script for Cantera
Basic usage:
'scons help' - print a description of user-specifiable options.
'scons build' - Compile Cantera and the language interfaces using
default options.
'scons clean' - Delete files created while building Cantera.
'[sudo] scons install' - Install Cantera.
'[sudo] scons uninstall' - Uninstall Cantera.
'scons test' - Run all tests which did not previously pass or for which the
results may have changed.
'scons test-reset' - Reset the passing status of all tests.
'scons test-clean' - Delete files created while running the tests.
'scons test-help' - List available tests.
'scons test-NAME' - Run the test named "NAME".
'scons <command> dump' - Dump the state of the SCons environment to the
screen instead of doing <action>, e.g.
'scons build dump'. For debugging purposes.
'scons samples' - Compile the C++ and Fortran samples.
'scons msi' - Build a Windows installer (.msi) for Cantera.
'scons sphinx' - Build the Sphinx documentation
'scons doxygen' - Build the Doxygen documentation
