luaoptions

Option handling for LuaLaTeX packages

This package has been extracted from lyluatex where it was originally developed as supporting functionality. However, as it turned out it is useful as a building block for LuaLaTeX packages in general, and the development of luaformatters made it clear that the option handling code had to be moved to a standalone package.

Initially there is no extensive documentation available since the package wasn't originally intended to be exposed to third-party packages or even end-users; the best sources of documentation are lyluatex and luaformatters codes, and the docstrings of luaoptions.lua and luaoptions-lib.lua.
