<p>Elemental typesetting functions can be be challenging to use directly
with complex documents. A <em class="dfn">macro</em> facility specifies how certain
routine operations, such as starting paragraphs, or printing headers and
footers, should be performed in terms of those low-level instructions.
Macros can be specific to one document or collected together into a
<em class="dfn">macro package</em> for use by many. Several macro packages available;
the most widely used are provided with <code class="code">groff</code>. They are
<samp class="file">man</samp>, <samp class="file">mdoc</samp>, <samp class="file">me</samp>, <samp class="file">mm</samp>, <samp class="file">mom</samp>, and
<samp class="file">ms</samp>.
