+Alliance has been succesfully build on Mac OS X.2 (Jaguar) (X.2.4)
 This is what is needed to build ALLIANCE:
    * get the developer tools.
      ( at least July 2002 version ... based on gcc 3)
-   * XDarwin (based on XFree86)
-     (at least version 1.1.0.1 based on XFree86 4.2.0.1)
+   * get Apple's X11.
    * install the openmotif3 package using fink.
      (http://fink.sourceforge.net)
 
 Then follow the same instructions as for any Unix workstation.

-All tools seem to work correctly, except OCR, so instead use
-the new router NERO, which works fine.

 # How to run this bench ? :
 # ===================================================================
-First of all, edit the Makefile and set the ALLIANCE_TOP variable to
-the directory where ALLIANCE is installed:  /usr/local, /opt
-or whatever.
+First of all, the ALLIANCE environment must be setted.
+Depending on your shell, source the alc_env.csh or alc_env.sh
+script.
 This done, you can run the entire process by typing:
 > make clean
 > make
