Platform independent method of getting directory information in lua

[Michael Bernstein <michael@...>]

I have a question regarding some functionality that lua may lack, and 
if in fact lua lacks it, how to go about it.

Here is my scenario.

I have an indeterminable number of lua scripts that are each objects in 
their own right.  Basically it allows one to customize the different 
objects used in gameplay with lua rather than having to recompile the 
objects each time they change.  My issue is as follows:

I thought a good idea would be to have a wrapper lua script that 
somehow gets all the object names (I really don't want to have to 
define them, since that just adds a layer of complexity for the end 
user.

Is there any platform independent way of getting this information?  I 
conceivably could use ifndef's and use platform dependent functions in 
c++ and then pass that onto lua, but that feels like a kludge overall.  
If anyone has any advice in regard to this, I'd greatly appreciate it.  
I hope I've just not read the manual entirely and have missed some 
function that would aid in it, but I have browsed it pretty well.  The 
whole issue is being platform independent.

Thanks in advance,
