From syslinux GSOC 2009 home page:
Finish the Lua engine
We already have a Lua interpreter integrated with the Syslinux build. However, right now it is not very useful. We need to create a set of bindings to the Syslinux functionality, and have an array of documentation and examples so users can use them.
This is not a documentation project, but the documentation deliverable will be particularly important for this one, since the intended target is system administrators, not developers.
