   IT WORKS!!!
 
   Please remove the following objects:
-  - directory ${LIBDIR}/ccfe/ccfe.menu     (the previous test menu)
-  - file      ${LIBDIR}/ccfe/it_works.txt  (this file)
+  - directory /usr/lib/ccfe/ccfe.menu     (the previous test menu)
+  - file      /usr/lib/ccfe/it_works.txt  (this file)
 
   The demo menu will still be available running the command
 
-    ${BINDIR}/ccfe demo
+    /usr/bin/ccfe demo
 
   but if you want to remove it, you have to delete the following directories:
-    ${LIBDIR}/ccfe/demo.menu
-    ${LIBDIR}/ccfe/demo.d
+    /usr/lib/ccfe/demo.menu
+    /usr/lib/ccfe/demo.d
 
   CCFE demos uses /bin/sh as shell interpreter, and they assume that it is a
   Bourne compatible shell. If it is not like this, please change the CCFE shell
-  in the ${ETCDIR}/ccfe.conf file.
+  in the /etc/ccfe.conf file.
 
   You can find documentation, samples and Licensing Information in the
-  directory ${DOCDIR}.
+  directory /usr/share/doc/ccfe.
 
 
   Enjoy!
