Harry,

Here is a complete cabal file for something I am working on now... it contains some libraries and three executables that use the library. It's a WIP for me BUt it works and I can even use it from Leksah by creating a workspace and adding this hexwax.cabal file as a Package.

It's long but concise!

I've written a library, and a simple program to demonstrate it. I can write
the cabal file for the library, but I can't get the executable section
right. How can I tell it to use the library defined herein?
