  IT WORKS!!!

  Please remove the following objects:
  - directory ${LIBDIR}/ccfe/ccfe.menu     (the previous test menu)
  - file      ${LIBDIR}/ccfe/it_works.txt  (this file)

  The demo menu will still be available running the command

    ${BINDIR}/ccfe demo

  but if you want to remove it, you have to delete the following directories:
    ${LIBDIR}/ccfe/demo.menu
    ${LIBDIR}/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.

  You can find documentation, samples and Licensing Information in the
  directory ${DOCDIR}.


  Enjoy!
