	Hi Bob,

  Thanks for bringing the discussion back on track.

  Nobody said it was.

  TeXLua -- just as LuaTeX -- has a Lua interface to kpathsea, called
"kpse": kpse.find_file(<some Lua file>) should return the file found by
kpsewhich, but you need to initialise the library, and I'm not able to
provide a working example at the moment.

  The full documentation for all of LuaTeX's extra Lua libraries is
available from "texdoc luatex", but you may find that the description is
sometimes concise to the extreme.
