--- After a few years using the code the large luat-inp.lua file
--- has been split up a bit. In the process some functionality was
--- dropped:
---
--- * support for reading lsr files
--- * selective scanning (subtrees)
--- * some public auxiliary functions were made private
---
--- TODO: os.getenv -> os.env[]
--- TODO: instances.[hashes,cnffiles,configurations,522]
--- TODO: check escaping in find etc, too much, too slow
-
--- 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!

-</code>
-TEXMFCACHE=$TMP;$TEMP;$TMPDIR;$TEMPDIR;$HOME;$TEXMFVAR;$VARTEXMF;.

-
-<p>Currently we do no locking when we write files. This is no real
-problem because most caching involves fonts and the chance of them
-being written at the same time is small. We also need to extend
-luatools with a recache feature.</p>

--- After a few years using the code the large luat-inp.lua file
--- has been split up a bit. In the process some functionality was
--- dropped:
---
--- * support for reading lsr files
--- * selective scanning (subtrees)
--- * some public auxiliary functions were made private
---
--- TODO: os.getenv -> os.env[]
--- TODO: instances.[hashes,cnffiles,configurations,522]
--- TODO: check escaping in find etc, too much, too slow
-
--- 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.
+-- In practice we will work within one tds tree, but i want to keep
+-- the option open to build tools that look at multiple trees, which is
+-- why we keep the tree specific data in a table. We used to pass the
+-- instance but for practical purposes we now avoid this and use a
+-- instance variable. We always have one instance active (sort of global).
