ENVIRONMENTS:
    NODE_TYPE       'sim' for CLI, 'ncp-sim' for NCP. The default is 'sim'.
    NODE_MODE       'rcp' for RCP mode, otherwise for standalone mode. The default is standalone mode.
    VERBOSE         1 to build or test verbosely. The default is 0.
    VIRTUAL_TIME    1 for virtual time, otherwise real time. The default is 1.
    THREAD_VERSION  1.1 for Thread 1.1 stack, 1.2 for Thread 1.2 stack. The default is 1.1.

COMMANDS:
    clean           Clean built files to prepare for new build.
    build           Build project for running tests. This can be used to rebuild the project for changes.
    cert            Run a single thread-cert test. ENVIRONMENTS should be the same as those given to build or update.
    cert_suite      Run a batch of thread-cert tests and summarize the test results. Only echo logs for failing tests.
    unit            Run all the unit tests. This should be called after simulation is built.
    expect          Run expect tests.
    help            Print this help.
