--- 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.
-
--- When libraries used here are updates you can run
---
--- mtxrun --selfmerge
---
--- to update the embedded code. After that you might need to run
---
--- mtxrun --selfupdate
---
--- to copy the new script (from scripts/context/lua) to location where
--- binaries are expected. If you want to remove the embedded code you can run
---
--- mtxxun --selfclean
-
--- 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}_

--- 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.
-
--- When libraries used here are updates you can run
---
--- mtxrun --selfmerge
---
--- to update the embedded code. After that you might need to run
---
--- mtxrun --selfupdate
---
--- to copy the new script (from scripts/context/lua) to location where
--- binaries are expected. If you want to remove the embedded code you can run
---
--- mtxxun --selfclean
-
--- 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)
