 facility.  The syntax is similar to that of formulae in most programming

 for example `tt(zcalc -#16)' (the `tt(#)' may have to be quoted, depending
 on the globbing options set).
 
+If the option `tt(-e)' is set, the function runs non-interactively:
+the arguments are treated as expressions to be evaluated as if entered
+interactively line by line.

 If the option `tt(-f)' is set, all numbers are treated as floating
 point, hence for example the expression `tt(3/4)' evaluates to 0.75
 rather than 0.  Options must appear in separate words.
