Extra-SLIB Packages
===================

  Several Scheme packages have been written using SLIB.  There are
several reasons why a package might not be included in the SLIB
distribution:
   * Because it requires special hardware or software which is not
     universal.

   * Because it is large and of limited interest to most Scheme users.

   * Because it has copying terms different enough from the other SLIB
     packages that its inclusion would cause confusion.

   * Because it is an application program, rather than a library module.

   * Because I have been too busy to integrate it.

  Once an optional package is installed (and an entry added to
`*catalog*', the `require' mechanism allows it to be called up and used
as easily as any other SLIB package.  Some optional packages (for which
`*catalog*' already has entries) available from SLIB sites are:

SLIB-PSD
     is a portable debugger for Scheme (requires emacs editor).

     With PSD, you can run a Scheme program in an Emacs buffer, set
     breakpoints, single step evaluation and access and modify the
     program's variables. It works by instrumenting the original source
     code, so it should run with any R4RS compliant Scheme. It has been
     tested with SCM, Elk 1.5, and the sci interpreter in the Scheme->C
     system, but should work with other Schemes with a minimal amount
     of porting, if at all. Includes documentation and user's manual.

     is a Scheme program which converts text among the JIS, EUC, and
     Shift-JIS Japanese character sets.
