doc
module*
Using `module*` allows the documentation submodule to refer to the implementation module.
One problem involved context that should not be included in a generated submodule, while another one was an issue with the previous repair to the shift to label phase.
scribble/lp2
Unlike `scribble/lp` a programm written with `scribble/lp2` can be used directly, due to its `doc` submodule.
