lated to a module
     `(bla blum)'.

     The normal way for a extension to be used is to write a small
     Scheme file that defines a module, and to load the extension into
     this module.  When the module is auto-loaded, the extension is
     loaded as well.  For example,

          (define-module (bla blum))
          
          (load-extension "libguile-bla-blum" "bla_init_blum")
