ConTeXt Standalone/Implementation

splitting binaries

files.lst :

# common
...
...
#luatex
...
...
#xetex
...

#pdftex

i can then use that (will make a script) that will install what is needed

mtxrun --script install --engine=xetex --platform=macosx-intel

and such (is we make luatex 'common' we have a scripting machinery)
