@doc{*
  This annotation takes two parameters. The first is a number. There should be
  an error from the line of the annotation plus this number. The second parameter 
  is the error message that the compiler should issue (or a similar message).
  The compiler checks if there is an error in the indicated line. If not,
  an error message is issued. That is, suppose the code
        @cep(1, "Expression expected)
        var k = 1 + ;
  is in a file being compiled. The compiler will point the error and print 
  a message that a metaobject pointed out that there is an error in the line 
  with the real error. If there were no error, the compiler would issue an 
  error telling that it itself should have pointed out an error in the line
  "var k = 1 + ;".
