if the only copyright license granted for the Haskell-readline code is GPL (which sounds true), then it has to stay GPL. If BSD was also given as permission (it's always possible to give more permissions for the parts of something that you hold the copyright to), then, no worries, Haskell-editline can be BSD.

Finding the author would be good if we could though, because she/he/they would most likely give us BSD permissions (just guessing :-)

Thanks all, that's pretty much what I expected. I'll try to track down the author and get BSD permissions from them. I'm having trouble accessing the history of the file hslibs/util/Readline.hsc (which was deleted before the cvs->darcs change). Can I access the pre-darcs cvs repo from somewhere? The documentation for ghc-6.4 says to use glass.cse.ogi.edu, but it looks like that server is no longer active. Also, from what I can tell, several people have made minor changes to that file (such as updating to the FFI standard or adding Haddock docs). How should I handle copyright attribution and getting permission with respect to contributors? Thanks, -Judah

completely mechanical changes or a single contributor contributing less than 15 lines of changes total is generally not significant for copyright.[1] The Haddock is more likely to be significant and you should probably find its author(s) too. ..although there's not very much readline docs (besides type-signatures) on http://www.haskell.org/ghc/docs/latest/html/libraries/index.html [1] http://www.gnu.org/prep/maintain/html_node/Legally-Significant.html ~Isaac
