-- 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.

-- to be done / considered
--
-- support for --exec or make it default
-- support for jar files (or maybe not, never used, too messy)
-- support for $RUBYINPUTS cum suis (if still needed)
-- remember for subruns: _CTX_K_V_#{original}_
