455: <h3>Ports Tree</h3>
456: <p>
1.1 beck 457: A ports tree archive is also provided. To extract:
458: <blockquote><pre>
1.7 bentley 459: # <kbd>cd /usr</kbd>
460: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1.1 beck 461: </pre></blockquote>
1.7 bentley 462: <p>
1.1 beck 463: Go read the <a href="faq/ports/index.html">ports</a> page
464: if you know nothing about ports
465: at this point. This text is not a manual of how to use ports.
466: Rather, it is a set of notes meant to kickstart the user on the
467: OpenBSD ports system.
468: <p>
469: The <i>ports/</i> directory represents a CVS checkout of our ports.
470: As with our complete source tree, our ports tree is available via
471: <a href="anoncvs.html">AnonCVS</a>.
472: So, in order to keep up to date with the -stable branch, you must make
473: the <i>ports/</i> tree available on a read-write medium and update the tree
474: with a command like:
475: <blockquote><pre>
1.7 bentley 476: # <kbd>cd /usr/ports</kbd>
1.15 jsg 477: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_6</kbd>
1.1 beck 478: </pre></blockquote>
1.7 bentley 479: <p>
1.1 beck 480: [Of course, you must replace the server name here with a nearby anoncvs
481: server.]
482: <p>
483: Note that most ports are available as packages on our mirrors. Updated
484: ports for the 6.6 release will be made available if problems arise.
485: <p>
486: If you're interested in seeing a port added, would like to help out, or just
487: would like to know more, the mailing list
488: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
