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.
