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.
