Hi folks, As discussed, I set up a darcs repository on haskell.org for us to put example code in. Anybody can obtain it by executing darcs get http://darcs.haskell.org/generics or if you have an existing account for the CVS/darcs repos at haskell.org, you can alternatively use darcs get darcs.haskell.org:/home/darcs/generics I have set up push messages to go to this list. We'll see whether that works in a moment when I push the LIGD code that was posted by James and Johan. There is also a README file with some comments re the directory structure of the repository. Darcs ~~~~~ If you are new to darcs, check out http://darcs.net/, where you can find binaries to download for a wide variety of architectures, a manual, and a wiki with lots of additional information. (For Fedora Core users, just execute "yum install darcs" as root - darcs is in Fedora Extras.) License ~~~~~~~ When looking at the source code, I noticed that it does not have any licencing information. If we want to develop a library that we expect end users to build applications with, it is absolutely crucial to properly licence the code. In particular, we must be very careful to not use any code from libraries that do not have an explicit licence (or a license that conflicts with whatever license terms we want for our end product). In addition, anybody who contributes patches needs to do that under the agreement that his or her code may be released under the licencing terms of the library that we develop. As we want to develop a sort of standard, I strongly suggest to use the New BSD Licence http://opensource.org/licenses/bsd-license.php, which is what GHC uses, too. It's called BSD3 in Cabal http://www.haskell.org/ghc/docs/latest/html/libraries/Cabal/Distribution-Lic.... James, Johan, Ralf, would you mind to put your LIGD code under this license? If you agree, please just put a file called LICENSE with the license text (copy from above URL) into the LIGD/ and LIGD.examples/ directories in the darcs repo. Manuel
