While platform-specific problems can often be handled purely in Lua, it sometimes happens that access to the native operating system API is required. For such tasks, Lua itself makes it possible to load extension modules written in C (or other languages provided that they can produce a dynamic library that exports a certain C-style function).

The present package aims to provide such an extension module that is usable from both Lua and LuaTeX and adds a small set of features not available otherwise. This release merely supports listing the fonts known to the operating system (this feature could usefully be integrated into the luaotfload package).
