Integrates the letter class with fancyhdr and geometry to automatically make letterhead stationery. Useful for 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.
