"""
SCons build script for Cantera
Basic usage:
'scons help' - Show this help message.
'scons build' - Compile Cantera and the language interfaces using
default options.
'scons clean' - Delete files created while building Cantera.
'scons install' - Install Cantera.
'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 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
Additional command options:
'scons help --options' - Print a description of user-specifiable options.
'scons help --list-options' - Print formatted list of available options.
'scons help --option=<opt>' - Print the description of a specific option
with name <opt>, for example
'scons help --option=prefix'
'scons <command> -j<X>' - Short form of '--jobs=<X>'. Run the <command> using '<X>'
parallel jobs, for example 'scons build -j4'
'scons <command> -s' - Short form of '--silent' (or '--quiet'). Suppresses output.
"""
# Note that 'scons help' supports additional command options that are intended for
# internal use (debugging or reST parsing of options) and thus are not listed above:
# --defaults ... list default values for all supported platforms
# --restructured-text ... format configuration as reST
# --dev ... add '-dev' to reST output
# --output=<fname> ... send output to file (reST only)
#
# Other features not listed above:
# 'scons sdist' - Build PyPI packages.
# 'scons <command> dump' - Dump the state of the SCons environment to the
# screen instead of doing <command>, for example
# 'scons build dump'. For debugging purposes.
# This f-string is deliberately here to trigger a SyntaxError when
# SConstruct is parsed by Python 2. This seems to be the most robust
# and simplest option that will reliably trigger an error in Python 2
# and provide actionable feedback for users.
f"""
Cantera must be built using Python 3.8 or higher. You can invoke SCons by executing
python3 `which scons`
followed by any desired options.
