1.15      grr        23: <p>
                     24: Anonymous CVS is a method of keeping your local copy of the OpenBSD source
                     25: tree up to date with respect to changes made to current OpenBSD sources.
1.14      downsj     26: <p>
1.15      grr        27: The major advantage of Anonymous CVS over other source code update
                     28: techniques is that it works directly against a central source code
                     29: repository or mirror.  This means that you have the full set of CVS
                     30: commands available to control merging and updating your changes with
                     31: other source changes and for performing diff's, change histories
                     32: and other queries against the central repository.
1.36      deraadt    33: <p>
                     34: You can use anoncvs to access our three main source repositories:
                     35: <strong>src</strong>, <strong>ports</strong>, and <strong>www</strong>.
                     36: <p>
1.43      deraadt    37: <h3><font color=#0000e0>CVS:</font></h3>
1.36      deraadt    38: <a href=why-cvs.html>
                     39: CVS is the source code control system used to manage the OpenBSD source tree.</a>
1.16      deraadt    40: It implements a central repository for all officially released source code
1.15      grr        41: and changes, while permitting developers to maintain local copies of the
                     42: source code with their working changes.  Developers with "write access"
                     43: can commit changes directly to the OpenBSD source tree, while "Anonymous
                     44: CVS" users have "read access" and can keep their local copies of the source
                     45: up to date and issue queries against the central depository.
                     46: <p>
1.22      niklas     47: The major strength of CVS is that it has the ability to perform intelligent
1.15      grr        48: merges of changes to the central repository with changes that you make to
                     49: your local copy.  This means that if you make a change to a module and
                     50: perform an update, your changes are not "blown away", rather CVS makes
                     51: best efforts to merge the changes made to the central sources with changes
                     52: you've made to your local copy.
                     53: <p>
                     54: In the event that the changes can't be completely merged, CVS provides a
                     55: "soft fallback", in terms of providing you with annotated changes to your
1.39      todd       56: local copy, preserving an unmodified copy of your version and continuing
1.15      grr        57: to update any other source modules you requested.
1.22      niklas     58: <p>
1.23      mickey     59: People who own an OpenBSD CD may have seen the CVS/ dirs on it.
1.22      niklas     60: Actually there is a reason, the CD has a checkout of the OpenBSD src/ module
1.23      mickey     61: usable to continue updating from.  Using this tree will results in a much
                     62: faster initial CVS update than a fresh checkout of the full OpenBSD
                     63: source tree.  There are two ways of using the CD:
                     64: <ul>
                     65: <li>copy the tree off it, (assuming the CD is mounted on /mnt):
1.22      niklas     66: <pre>
1.23      mickey     67:        <b>#</b> cd /mnt; cp -Rp CVS Makefile bin distrib etc games gnu \
                     68:        <b>&gt;</b> include kerberosIV lib libexec lkm regress sbin share \
                     69:        <b>&gt;</b> sys usr.bin usr.sbin /usr/src
1.22      niklas     70: </pre>
1.23      mickey     71: <li>use a union mount with the CD below a writable directory.
1.22      niklas     72: <pre>
1.23      mickey     73:        <b>#</b> mount -t union -o -b /mnt /usr/src
1.22      niklas     74: </pre>
1.23      mickey     75: </ul>
1.22      niklas     76: After this, /usr/src will be a nice checkout area where all cvs(1) commands
                     77: will work OK.

1.39      todd      102: To summarize, the real strength of using Anonymous CVS is that it is
1.15      grr       103: a "tolerant" source code control system - it <strong>respects</strong>
                    104: changes that you have made to your local sources and makes <strong>
