// ---------- "harvest proof email" -----------
// These JavaScript functions take an email
// address as a variable, passed from
// print_mailto_begin to create the first
// part of the  mailto link.  Call 
// print_mailto_end to finish it off. 
// If JavaScript is turned off, the mailto
// link simply disappears, leaving behind
// an email address that can be cut and pasted.
