So do I. A system-wide configuration file is a good thing to have (and
better placed in /etc/ than in JED_ROOT/lib).

However, as I see it, there are up to 4 parties that might want to
configure/setup jed:

  * jed standard distribution  --> JED_ROOT/site.sl  
                                   (and currently JED_ROOT/jed.rc as
                                   fallback)
                                   
  * jed package maintainer     --> /etc/jed.conf
    (e.g. for jed on Debian)       (currently calling /etc/jed-init.d/...)
                                   or /usr/etc/jed.conf
    
  * Site administrator         --> /usr/local/etc/jed.conf

  * User                       --> ~/.jedrc (or, with home-lib.sl, 
                                            ~/.jed/jed.rc or ~/.jed/.jedrc)


To allow all these to contribute to jed customization, I suggest a change
in site.sl:


  if (strlen(expand_jedlib_file("defaults.sl")))
    () = evalfile("defaults");
  #ifdef UNIX
- else foreach (["/etc/jed.conf", "/usr/local/etc/jed.conf", "/usr/etc/jed.conf"])
+ foreach (["/etc/jed.conf", "/usr/etc/jed.conf", "/usr/local/etc/jed.conf"])
  {
     $1 = ();
     if (1 == file_status ($1))
       {
  	() = evalfile ($1);
-  	break;
       }
  }
  #endif


Should we keep the test for defaults.sl under UNIX or could it be skipped?

On Windows the situation differs and JED_ROOT/lib/defaults.sl
might be a sensible place for configuration there. (better ideas?)

So we will do this for now.

This would be nice. IMHO, all remaining non-default settings could be
transferred to site.sl and jed.rc simply kept as a template and example
(which would make Default_Jedrc_Startup_File obsolete).
