I wonder what software licence I can use to release my application. I've developed some education tool with the following dependencies: % ghci Main.hs GHCi, version 6.10.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer ... linking ... done. Loading package base ... linking ... done. Ok, modules loaded: Main, UI, Lambda, Lambda.Eval, Lambda.Zipper, Lambda.Show, Lambda.Parser, Lambda.Common.

Loading package glade-0.10.0 ... linking ... done. I just don't know the options and I think licensing is subtle enough to ask for suggestions. Thanks in advance. -- Victor
