@doc{*
  Annotation 'doc' can be attached to any declaration, including
  the program and packages
  
  This metaobject generates code that writes to a file the value 
  of a local or field that is parameter to the annotation.
  In fact, the last five values of the variable are kept in the file, 
  which is specific to every variable. The
  file is keepValue_varName.txt in the directory --tmp of a directory 
  whose name is the prototype in which the annotation is.
