--- 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.
