   I believe there is activity going on at CMU to create a byte
   compiler for Sieve scripts.  Perhaps that will be a bit more verbose
   about script errors.

We currently use yacc (or bison) to parse Sieve scripts; the bytecode
work isn't currently expected to change this.  We basically report the
parse errors that Yacc gives us.

It was initially anticipated that the majority of Sieve scripts would
be generated by some other program, and thus errors would be kept to a
minimum.
