Command-line reference

Commands

Command	Purpose
`check [PRODUCT\|FILE]`	Strictly check a project product or `.tl` file
`run [PRODUCT\|FILE]`	Build and run through LLVM native
`build [PRODUCT\|FILE]`	Build without launching
`test [PRODUCT]`	Build and run a `TestSuite` product
`lock`	Resolve dependencies and write `tulam.lock`
`project show`	Show normalized project selection
`project graph`	Show the dependency-first module graph
`explain CODE`	Explain a registered diagnostic code
`stages`	List registered compiler stages

Running tulam with no command opens the canonical compiled shell. It accepts persistent declarations and expressions, discovers project context, and executes through an isolated LLVM ORC worker. :help lists shell commands.
