HOWTO: create custom fortune cookies files
  Open your favourite editor and add the strings that you want to be shown 
    when running "fortune" in terminal. 
  BE SURE to add a single line with only the character '%' in it, between 
    every string,  AND AFTER the very last fortunes entry.
  Save this file to whatever file name you want; as an example: "yourlist".
  When done adding strings, run the command  "strfile -c % yourlist yourlist.dat". 
  This will create a .dat file for your fortune file, which contains a header 
    structure and a table of file offsets for each group of lines. 
  This allows random access of the strings.
  Run "fortune yourlist" to eat the fruit of your work. That's it! 
  Oh, and one more thing: if you change anything in "yourfile", 
    you will need to repeat the "strfile -c % yourlist yourlist.dat".
