The mapping of libraries to a file hierarchy described by this SRFI is
quite generic, and will work with all dialects where normalized library
names are symbol lists (sans versioning).

What will not work is putting files from conflicting dialects in the
same place (SCHEME_LIBRARY_SEARCH_PATHS in current draft).

So if this SRFI is to be language-agnostic, it should specify how
libraries from different dialects (e.g. R^NRS, SLIB) are to co-exist in
a single location. If not then a single dialect should be chosen
and SCHEME_LIBRARY_SEARCH_PATHS renamed to reflect that choice.
Alternatively this whole part can be dropped.
