  It is only a test driver, to allow testing different options, and
all lightning
instructions on different configurations.
  It is useful to write small tests and see what could would be generated.

  It just generates an executable buffer in memory, and executes it, unless
the ".disasm" option is used to disassemble a small code generation. It
does not output anything much more meaningful, but yes, one of the
TODOs in lightning is to generate usable object or executable files.
