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! ---- -- Initial hexwax.cabal generated by cabal init. For further -- documentation, see http://haskell.org/cabal/users-guide/ -- The name of the package. name: hexwax -- The package version.

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?
