The advice in REDME.Debian is

  jed.rc       user startup configuration (move the jed.rc from the
               examples/ here and modify to your needs)

where the example file contains the code to select an emulation.
A minimalistic jed.rc could look like:

  % load emulation
  require("emacs");
  %require("cua");
  
  % change keybindings
  setkey("newline_indent", "^M"); % correct mouse-insertion problem

The problem is that:

1. Only *one* emulation file should be loaded

   - in order to speed up jed startup
  
   - to prevent incompatibilities, or definitions that are not
     overridden in a different emulation mode.
      
2. The emulation mode should be configurable by the user.

3. Jed needs to use a "sensible" emulation mode also if there is no user
   setting. 
  
The upstream solution is provide a fallback, if there is no indication
that the user has choosen an emulation. To achieve this, an emulation
mode sets the variable `_Jed_Emulation`. If this variable is not set, the
mode defined in the variable `_Jed_Default_Emulation` is evaluated
(naturally, this can only happen after evaluating jed.rc).

(On Debian, `_Jed_Default_Emulation` is set in /etc/jed.d/05jed-common.sl
and can be configured by the sysadmin.)
  

I will update README.Debian and README.Debian-startup to make this more
clear.
