+-- 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.
+

+-- 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 control.

+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>

+<l n='lpeg'/> code to it.</p>
