[NTG-context] Using Lua files in project structure

I'm writing a project in ConTeXt MKIV and I want to load some (pure) Lua libraries and bindings (defining \ctxlua and the like). For instance, I have the file foo.lua with some macros and I want to use them in my project. Something like this: \startproject project %\component foo.lua %This does not work %\environment foo.lua %This does not work %\input foo.lua %This does not work %\directlua{dofile("foo.lua")} %This does not work even when the project file and foo.lua are in the same folder. \stopproject What should I do? Thank you in advance.
