naming of directories for the new libraries

The Hugs counterpart of a package is a directory that can be put in the search path. Currently I'm using two: libraries - corresponding to the new hierarchical libraries packages base, haskell98 and haskell-src oldlib - a flat directory corresponding to hslibs and lib/exts Compilers don't like huge packages, but that doesn't apply to an interpreter. Still, maybe we'll need more packages in the future, so to allow for future expansion I'm thinking of renaming these libraries -> libraries/core oldlib -> libraries/compat More to type in -P though (maybe put them in lib?)
