>SVN (Subversion) is a tool used by many software developers to manage changes
within their source code tree. SVN provides the means to store not only the
current version of a piece of source code, but a record of all changes (and who
made those changes) that have occurred to that source code. Use of SVN is
particularly common on projects with multiple developers, since SVN ensures
changes made by one developer are not accidentally removed when another
developer posts their changes to the source tree. The Bochs source code and
documentation are available using SVN<A

>When you have SVN installed, the first step is to do a checkout. The initial
checkout command is long and ugly, but usually you only have to do it
once. The example below shows the SVN checkout process of the Bochs trunk in Unix.
On the Windows platform, you can download a SVN client from

of the SVN-controlled files. As it checks through the source directories, it
will list files that have changed, with a single letter before the name that
tells the status of that file. The most common status letters are listed
