results in a much faster initial CVS update than you could expect from

a fresh checkout of the full OpenBSD source tree.

A ports tree archive is also provided. To extract:

<p>

# <strong>cd /usr</strong>

# <kbd>cd /usr</kbd>

# <strong>tar xvfz /tmp/ports.tar.gz</strong>

# <kbd>tar xvfz /tmp/ports.tar.gz</kbd>

</pre></ul>

The <i>ports/</i> subdirectory is a checkout of the OpenBSD ports tree. Go

read the <a href="faq/ports/index.html">ports</a> page

OpenBSD ports system.

<p>

The <i>ports/</i> directory represents a CVS (see the manpage for

cvs(1)</a> if

you aren't familiar with CVS) checkout of our ports. As with our complete

source tree, our ports tree is available via

Line 889

Line 879

available on a read-write medium and update the tree with a command

like:

<p>

# <strong>cd /usr/ports</strong>

# <strong>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_5_6</strong>

</pre></ul>

</pre></blockquote>

<p>

[Of course, you must replace the server name here with a nearby anoncvs

server.]

If you're interested in seeing a port added, would like to help out, or just

would like to know more, the mailing list

<a href="mail.html">ports@openbsd.org</a> is a good place to know.
