1.3       benno      90:        <li>Added support in the kernel and libc for timecounting in
                     91:        userland, eliminating the need for a context switch everytime a
                     92:        process requests the current time, thereby improving speed and
                     93:        responsiveness in programs which make many <a

                   1013: at this point.  This text is not a manual of how to use ports.
                   1014: Rather, it is a set of notes meant to kickstart the user on the
                   1015: OpenBSD ports system.
                   1016: <p>
                   1017: The <i>ports/</i> directory represents a CVS checkout of our ports.
                   1018: As with our complete source tree, our ports tree is available via
                   1019: <a href="anoncvs.html">AnonCVS</a>.
                   1020: So, in order to keep up to date with the -stable branch, you must make
                   1021: the <i>ports/</i> tree available on a read-write medium and update the tree
                   1022: with a command like:
                   1023: <blockquote><pre>
                   1024: # <kbd>cd /usr/ports</kbd>
                   1025: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_8</kbd>
                   1026: </pre></blockquote>
                   1027: <p>
                   1028: [Of course, you must replace the server name here with a nearby anoncvs
                   1029: server.]
                   1030: <p>
                   1031: Note that most ports are available as packages on our mirrors. Updated
                   1032: ports for the 6.8 release will be made available if problems arise.
                   1033: <p>
                   1034: If you're interested in seeing a port added, would like to help out, or just
                   1035: would like to know more, the mailing list
                   1036: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
