The version 1.00 is finally here (work on STklos started 10 years before ...).
The main difference with this version and the pre-1.0
ones is that it does not integrate GTK+ 1.x support. In fact, GTK+
support is now available through several ScmPkg packages. Otherwise:

    * Complete rewriting of GMP-lite, the provided gmp compatible
      package for system which does not provide it

      loaded dynamically
    * Configuration files location can now be changed

          o ensure-directories-exist
    * Bug fixes

    This is a version with important changes to support

    threads and Posix threads (aka pthreads). LURC threads are
    implemented using the LURC library, the Light ULM/Reactive library
    for C developed at INRIA. LURC supports the creation of
    synchronous cooperative threads, synchronizing and communicating
    with each other using signals in a deterministic scheduler (see
    http://www-sop.inria.fr/mimosa/Stephane.Epardaud/lurc for
    details).

      This implies some (compatible) changes in the hash-tables
      function names.
    * New primitives
          o finite?
          o infinite?
