How can I write letters in LaTeX?

It is easy to write professional-looking letters using LaTeX. Here's the basic template:

	\documentclass{letter}
	\signature{James Tetazoo}
	\address{3 Ames Street\\Cambridge, MA\\02139}
	\begin{document}
	  \begin{letter}{Jack Florey\\
	5 East Street\\
	New York City, NY\\
	12345}

	\opening{Dear Jack,}

	body of letter here..

	\closing{Sincerely,}

	  \end{letter}
	\end{document}

\address defines what will be printed as your return address; \\ is used to separare lines. The address of the recipient is specified in the braces right after \begin{letter}.

If you want to have a "Cc" list at the bottom of your letter, this is easily done. Just put

	\cc{person1\\person2\\person3}

after the \closing{}; there can be as many cc'd people as you want.
