     Project:          slippery chicken (algorithmic composition)

     Purpose:          Definition of the user-changeable configuration data and
                       globals for internal programme use. See top of cmn.lsp and
                       osc-sc-bsd.lsp for a few more globals relevant to
                       functionality in their respective packages.

[ Top ] [ Global Parameters ]

DESCRIPTION

     A global to hold various user-settable configuration settings.  Use e.g.
     (set-sc-config 'default-dir "~/Desktop") or (get-sc-config 'default-dir) to
     set or query the settings.
