-
--- TODO: os.getenv -> os.env[]
--- TODO: instances.[hashes,cnffiles,configurations,522] -> ipairs (alles check, sneller)
--- TODO: check escaping in find etc, too much, too slow
-
--- This is the first code I wrote for LuaTeX, so it needs some cleanup.
-
--- 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.

--- This script is based on texmfstart.rb but does not use kpsewhich to
--- locate files. Although kpse is a library it never came to opening up
--- its interface to other programs (esp scripting languages) and so we
--- do it ourselves. The lua variant evolved out of an experimental ruby
--- one. Interesting is that using a scripting language instead of c does
--- not have a speed penalty. Actually the lua variant is more efficient,
--- especially when multiple calls to kpsewhich are involved. The lua
--- library also gives way more ocntrol.
