Exporting an #include from one package to another?
Is there a way to package up an #include like to share across (be #include'd into) various other haskell packages? I have some standard templates for type class instances that I can't define as instances without creating lots of overlapping instances. I can write an include file easily enough, but I don't know how to get other packages to find and #include that include file. - Conal

Yes. This is partly what the "install-includes:" field in the .cabal file is for. Each client has to #include it explicitly of course, but the include search path should be set up to make that work. Duncan
