Folks, I've updated the document at http://www.haskell.org/~simonmar/libraries/libraries.html to reflect some changes in how the libraries situation is evolving. This document is the central place where the workings of the hierarchical library system is described: it discusses how new libraries are contributed, where they live, what form they take and so on. The document is also in CVS (fptools/libraries/doc/libraries.sgml). Previously, we talked about the "Core Libraries" which were all going to be kept in one place (fptools/libraries), and this has pretty much been the situation up to now. But from here on, I expect things to become more distributed: people will maintain their own libraries and do releases independently of the compilers, and when we have a separate library infrastructure there will be no need for libraries to reside in the fptools tree. So with this in mind, the document now talks about "Reference Libraries". It is more clear about how names in the hierarchy are allocated (namely by asking on libraries@haskell.org), and it has a full list of what names have been allocated so far, who maintains those libraries and where to get the code. The evolution of a library infrastructure will have an impact on much of this, so I suggest that this document is the right place to record the results of that discussion (if/when there are some!). Comments welcome, as usual. Cheers, Simon
