    FreeBSD Glossary Terms
	Please keep this file sorted alphabetically/ASCIIly by glossterm.

	glossterms that are acronyms should have two entries - one for
	the expanded acronym and another for the acronym itself.  The
	second of these should reference the entry for the expanded acronym
	via a glosssee element.  For example:

	<glossentry>
	  <glossterm>FUBAR</glossterm>
	  <glosssee otherterm="fubar-glossary">
	</glossentry>

	<glossentry id="fubar-glossary">
	  <glossterm>Fuc... Up Beyond All Recognition</glossterm>
	  <acronym>FUBAR</acronym>
	  <glossdef>
	    <para>Broken.</para>
	  </glossdef>
	</glossentry>

	Note that in this instance, the expanded acronym sorts below the
	unexpanded acronym.  That's OK.

	Finally, id attribute values should end in the string
	"-glossary" to avoid conflicting with id attribute values in
	the main text.
