+writing letters, fax, and memos.  You can set up an address book using wrapper
+macros.  You put all the information for a person into a wrapper and then put
+the wrapper in a document.  The class handles letterheads automatically.  You
+place the object for the letterhead (picture, information, etc.) in a box and
+all sizing is set automatically.")
