Writing a formal letter is not always a simple thing. Even though composing the content of the letter may only take a few minutes, creating the actual document and getting the formatting right takes much much more time than it really should. This is where markdownletter enters the story.

Since formal letters need to look, well, formal you do not want to add more formatting than needed. With markdownletter you can write your letters in Markdown while following a few conventions. When you're done you can create a pdf document which you can then print right away.
