1.1 beck 447: Both of these trees are a regular CVS checkout. Using these trees it
448: is possible to get a head-start on using the anoncvs servers as
449: described <a href="anoncvs.html">here</a>.
450: Using these files
451: results in a much faster initial CVS update than you could expect from
452: a fresh checkout of the full OpenBSD source tree.

458: <h3>Ports Tree</h3>
459: <p>
1.1 beck 460: A ports tree archive is also provided. To extract:
461: <blockquote><pre>
1.7 bentley 462: # <kbd>cd /usr</kbd>
463: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1.1 beck 464: </pre></blockquote>

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