> Synex's MacEnvelope is implemented as both an application and a DA.
> The application is used to specify the default content and locations
> of the address blocks, graphics, and messages on the envelope. You
> can place these anywhere you like, and there is an option that
> superimposes postal guidelines so you don't place anything in the
> clear zones. As with KiwiEnvelopes!, you have font control over
> entire text fields only, not individual characters.
>
> When you access the DA, the contents of the Clipboard are
> automatically pasted into the mailing-address block on the envelope
> template. You can drag any of the envelope elements to a new
> position or change the text.
