This command compiles the given target, along with their dependencies,
into an executable using the WebAssembly code generation backend.

Usage:
  v -b wasm [-options] ['run']  [run options]


For more general build help, see also `v help build`.

# Interfacing WebAssembly code generation, passing options to it:
   -wasm-validate
      After compiling the WebAssembly module, execute wasm-validate to validate the module.
      Useful for debugging the compiler.

   -wasm-stack-top
      Overrides the default stack_top value used by the WebAssembly compiler.
      Useful for some platforms with unusual memory requirements.

   -d no_imports
      Removes the default imports from the builtins. Useful for embedded targets where
      you can't control the imports.

   -os , -target-os 
      Change the target WebAssembly execution environment that V compiles for.

      The `wasi` target is the default execution environment.
        When targeting WASI, the generated WebAssembly module can be run in a variety
		of environments that support the WASI specification.
        WASI provides a standardized interface to interact with the host operating system,
		allowing WebAssembly modules to perform tasks like file I/O, networking, and more.
        The specific version of the WASI specification targeted by V is 'wasi_snapshot_preview1'.

      The `browser` target is an experimental environment that compiles for a stripped down
	    builtin, for use in browsers. The produced WebAssembly module will have functions
		exported that are `pub` and inside the `module main`. See `examples/wasm/mandelbrot`
		for an example.
