  Why does everybody assume "org" is the "main" module when it's not?  It's
not "org" with "conman.syslog" as a submodule, it's "org.conman.syslog". 
The first two levels, "org.conman" just namespace my modules.

  Geeze, I might have to make "org.flummux.syslog" just to prove the point!

  That's an interesting solution, but how many github projects/Lua modules
will that work with?
