MatD - Matlab external interface bindings for D

[Rainer Schuetze]

Hi,

I have not tried it with the MatLab libraries, but optlink can only 
handle libraries in the omf-format. Libraries in other formats are 
either ignored (in the best case) or cause optlink to exit without 
error, but also without a generated executable.

Trass3r probably used coffimplib 
(ftp://ftp.digitalmars.com/coffimplib.zip) to convert the microsoft 
compatible import libraries to omf format to help optlink.
