Trivial Templating

Posted by evanx on July 9, 2010 at 10:20 AM PDT

Notwithstanding the fact that anyone in their right mind (which rules me out) would use Apache Velocity or FreeMarker for templating, we present a trivial templating helper class, where for instance we have an HTML template as follows to send a confirmation email to a customer.
