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.

<para>An approach to processor design where the operations the hardware

This can lead to lower power consumption, fewer transistors and in

some cases, better performance and increased code density. Examples

of RISC processors include the Alpha, &sparc;, &arm; and

&powerpc;.</para>

<para>A direct copying of files within the CVS repository.</para>
|
|
|
|
<para>Without a repocopy, if a file needed to be copied or
|
|
moved to another place in the repository, the committer would
|
|
run <command>cvs add</command> to put the file in its new
|
|
location, and then <command>cvs rm</command> on the old file
|
|
if the old copy was being removed.</para>
|
|
|
|
<para>The disadvantage of this method is that the history
|
|
(i.e. the entries in the CVS logs) of the file would not be
|
|
copied to the new location. As the &os; Project considers
|
|
this history very useful, a repository copy is often used
|
|
instead. This is a process where one of the repository meisters
|
|
will copy the files directly within the repository, rather than
|
|
using the &man.cvs.1; program.</para>
