\chapter{Extensions}

The letter module provides a special type of files, called extensions.
They provide functions that could be used by different files like the
labels for each language (\filename{label.nle}) or extra features
like page optimization (\filename{optimize.nle}).

You can load extension files either with the letter module and write
their names as arguments to the \type{extension} key or afterwards in
your file with the \type{\useletterextension} command.

\setup[useletterextension]

The module itself comes with the following extensions:

\starttabulate[|Bl|p|]
