Hugs and the new libs

I've got most of the hierarchical libraries working with Hugs. The main things missing are the new array stuff, Foreign (and things that need it) and the new Read implementation. To try it out: - get hugs98 and libraries from CVS. - recompile Hugs to get some recent bug fixes. - in hugs98/src/unix, run convert_libraries <directory where libraries lives> This will fill in hugs98/libraries with converted modules, and also create a directory hugs98/oldlib full of stubs for compatability with the old Hugs libraries. - Run hugs with hugs -P../../libraries:../../oldlib Some modules also need -98 The conversion script is an ugly kludge, but it mostly works.
