+-- 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.

+The find based parser can be found in l-xml-edu.lua along with other older code.</p>

+took 12.5 seconds to load (1.5 for file io and the rest for tree building). With
+the <l n='lpeg'/> implementation we got that down to less 7.3 seconds. Loading the 14
+<l n='context'/> interface definition files (2.6 meg) went down from 1.05 seconds to 0.55.</p>
+
+<p>Next comes the parser. The rather messy doctype definition comes in many
+disguises so it is no surprice that later on have to dedicate quite some
+<l n='lpeg'/> code to it.</p>

+-- This lib is multi-purpose and can be loaded again later on so that
+-- additional functionality becomes available. We will split this
+-- module in components when we're done with prototyping.
+
+-- 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.
+
+-- Beware, loading and saving is overloaded in luat-tmp!
