| <p><span class="bodyBlack"> | |
| The Concurrent Versions System (CVS) provides network-transparent source | |
| control for groups of developers. CVS has four basic functions: | |
| </span></p> | |
| <table cellspacing="2" cellpadding="2" border="0"><tr><td height="5" colspan="2"></td></tr><span class="bodyGrey"> | |
| <LI>Maintains a history of all changes made to each directory tree it manages</LI> | |
| <LI>Provides hooks to support process control and change control</LI> | |
| <LI>Provides reliable access to its directory trees from remote hosts using Internet protocols</LI> | |
| <LI>Supports parallel development allowing more than one developer to work on the same sources at the same time</LI> | |
| </span></table> | |
| <p><span class="bodyBlack"> | |
| All the OpenEJB source code, documentation, and other files are in a CVS | |
| repository on a server at Codehaus. To access the repository and | |
| download the source code and other files, you need a cvs client. | |
| </span></p> | |
| <a name="whereiscvs"><h2>Where can I get CVS?</h2></a> | |
| <p><span class="bodyBlack"> | |
| If you are on a Linux machine, you most likely already have cvs. To | |
| find out if cvs is intalled, type the following command at a prompt: | |
| <br><br> | |
| <span class="command">which cvs</span> | |
| </span></p> | |
| <p><span class="bodyBlack"> | |
| If you are one a Windows machine, you will need to download the CVS command-line | |
| client <a href="http://ftp.cvshome.org/win32/cvs1-11-1p1.zip">for Windows</a>. | |
| </span></p> | |
| <p><span class="bodyBlack"> | |
| The CVS command line client is available on many operating systems. | |
| Choose the CVS client that's right for your OS at the official | |
| <a href="http://www.cvshome.org/downloads.html">CVS download</a> | |
| page. | |
| </span></p> | |
| <a name="installingcvs"><h2>How do I install CVS?</h2></a> | |
| <p><span class="bodyBlack"> | |
| There is no "Install Shield" for cvs. You just put the cvs executable in | |
| any directory and then include that directory in your PATH system | |
| variable. Then you can execute cvs commands from anywhere in your | |
| command shell. | |
| </span></p> | |
| <a name="path"><h3>Set the PATH variable</h3></a> | |
| <p><span class="bodyBlack"> | |
| To set the PATH variable on a Windows machine, execute the following command | |
| in a command prompt.<br><br> | |
| <span class="command">set PATH=%PATH%;C:\the\path\where\cvs\is</span> | |
| </span></p> | |
| <a name="cvsroot"><h3>Set the CVSROOT variable</h3></a> | |
| <p><span class="bodyBlack"> | |
| To execute cvs commands against a CVS repository, you must | |
| tell cvs where the repository is by setting its location in a CVSROOT | |
| evironment variable, or by specifying it in your command with the cvs -d option. | |
| </span></p> | |
| <p><span class="bodyBlack"> | |
| To set the CVSROOT variable on a Windows machine so that it points toward | |
| the OpenEJB cvs at Codehaus, execute the following command in a command | |
| prompt.<br><br> | |
| <span class="command">set CVSROOT=:pserver:anon@cvs.openejb.codehaus.org:/scm/openejb</span> | |
| </span></p> | |
| <a name="home"><h3>Set the HOME variable</h3></a> | |
| <p><span class="bodyBlack"> | |
| The first time you access a particular CVS repository, you must first login | |
| to the server hosting the repository. You can do this with the 'cvs login' | |
| command, but before doing this you need to set another environment variable. | |
| CVS needs to know where to put your login information, for this you must set | |
| the HOME environment variable on your OS or in your shell.<br><br> | |
| If you are on a Linux/Unix machine, this will already be set, but if you are | |
| on a Windows machine, you will most likely need to do this manually. | |
| </span></p> | |
| <p><span class="bodyBlack"> | |
| To set the HOME variable on a Windows machine, execute the following command | |
| in a command prompt.<br><br> | |
| <span class="command">set HOME=C:\any\directory\works</span> | |
