--- TODO: os.getenv -> os.env[]
--- TODO: instances.[hashes,cnffiles,configurations,522]

--- This lib is multi-purpose and can be loaded again later on so that

--- 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
