We’re evaluating license compatibility of JRuby and ran across the FFI
code
lib/ruby/site_ruby/shared/ffi/ffi.rb
“… a recipient may use your version of this file under the terms of
any one of the CPL, the GPL or the LGPL.”
awesome. we like CPL.
then, in
lib/ruby/site_ruby/shared/ffi/ffi.rb
“you can redistribute it and/or modify it under the terms of the GNU
Lesser General Public License version 3”
