+-- 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.
