Re: How to tell if running script directly?

[<tonyp@...>]

Seems like a great solution!!! Thanks.  (I tried it and it works fine in
every case.  I also tried it with redirection, no problem.)

It also has the right 'mentality' for the latest Lua way of handling
modules.

 (This is 5.2, don't know 5.1 situation)

 If some code is called through require, then the chunk has the name given
to require as it's first argument, if executed, there are no arguments to
the chunk.

 So, for testing, I do

 local requirename = …
 if requirename then
 return moduletable
 end

 --tests go here

 Thanks,
 Kev
