+-- TODO: os.getenv -> os.env[]

+
+-- This lib is multi-purpose and can be loaded again later on so that
+-- additional functionality becomes available. We will split thislogs.report("fileio",
+-- module in components once we're done with prototyping. This is the
+-- first code I wrote for LuaTeX, so it needs some cleanup. Before changing
+-- something in this module one can best check with Taco or Hans first; there
+-- is some nasty trickery going on that relates to traditional kpse support.
+
+-- To be considered: hash key lowercase, first entry in table filename
+-- (any case), rest paths (so no need for optimization). Or maybe a
+-- separate table that matches lowercase names to mixed case when
+-- present. In that case the lower() cases can go away. I will do that
+-- only when we run into problems with names ... well ... Iwona-Regular.
+
+-- Beware, loading and saving is overloaded in luat-tmp!
