[Nasm-users] Directive for "file exists"

[<ait...@wa...>]

Hi,

In my project I am dealing with different language string catalogs, and 
it would be of use if there would be a directive that checks the 
existence of certain file to be included, is there a way to do this?
Something like
%ifexists  "filename"
%ifnexists "filename"
...
%endif

Cheers,
Aitor
