The molt-app crate provides a command line tool for use in development and experimentation. The command line tool, called molt, has several subcommands:

molt shell executes scripts and provides an interactive REPL.

molt test executes Molt test suites, most notably Molt's own test suite.

molt bench executes Molt benchmarks. This tool is experimental, and is primarily for use in optimizing molt itself.

Note: the molt-shell crate provides the same features for use with customized Molt interpreters.
