How do I read directories ?

[DirtyFinger <dirtyfinger@...>]

Hi,

   how can I read the content of a directory ?

   I'm writing some scripts for the DirectConnect Hub-software
   'PtokaX' which uses LUA for scripting.
   And one of my scripts is a bit larger and for the fun of it I built
   in localization. :)
   Different languages are stored in files named language.lan .
   Now I just want to be able to show and see which languagefiles are
   avaiable.
   How do I do it  ?
   The only examples I found used some c-libraries or external tools.

Thx,
    Armin
