The GHC Team

The success of GHC has a lot to do with the large band of highly talented people who contribute to it; this page is mainly to acknowledge those contributions but also to give users of GHC an idea of "who is responsible for what".

Porters/Packagers (no particular order)

The following table lists the people who have generously agreed to be responsible for the GHC port to a particular platform, or to produce binary packages for a certain platform.
