<p>GPS offers the possibility for multiple developers to work on the same project,
through the integration of version control systems (VCS). Each project can be
associated to a VCS, through the <code>VCS</code> tab in the Project properties
editor. See <a href="The-Project-Properties-Editor.html#The-Project-Properties-Editor">The Project Properties Editor</a>.
</p>
<p>GPS does not come with any version control system: it uses underlying
command-line systems such as Subversion or ClearCase to perform
the low level operations, and provides a high level user interface on
top of them. Be sure to have a properly installed version control
system before enabling it under GPS.
</p>
<p>The systems that are supported out of the box in GPS are:
</p>
<dl compact="compact">
<dt><b>Auto</b></dt>
<dd><a name="index-VCS_002c-auto"></a>
<p>GPS can be setup to auto-detect the actual VCS to use for each
project. This is done by selecting <code>Auto</code> in the <code>VCS</code> tab
of the Project properties editor. See <a href="The-Project-Properties-Editor.html#The-Project-Properties-Editor">The Project Properties Editor</a>.
This is also the default behavior when no VCS is specified in the project.
</p>
</dd>
<dt><b>ClearCase</b></dt>
<dd><a name="index-VCS_002c-ClearCase"></a>
<p>The standard ClearCase interface, which is built-in and uses a generic GPS
terminology for VCS operations.
</p>
<p>Note that, at the moment, only Snapshot Views are supported in the
ClearCase integration; Dynamic Views are not supported.
</p>
</dd>
<dt><b>ClearCase Native</b></dt>
<dd><a name="index-VCS_002c-ClearCase-Native"></a>
<p>Which is fully customizable and uses by default the terminology
specific to ClearCase.
</p>
<p>Note that, at the moment, only Snapshot Views are supported in the
ClearCase integration; Dynamic Views are not supported.
</p>
</dd>
<dt><b>CVS</b></dt>
<dd><a name="index-VCS_002c-CVS"></a>
<p>The Concurrent Version System.
</p>
<p>GPS needs a corresponding <code>patch</code> command that usually comes with it.
</p>
</dd>
<dt><b>Git</b></dt>
<dd><a name="index-VCS_002c-Git"></a>
<p>Distributed fast source code management. Support for Git on GPS is
partial. Basic commands are supported but the full power of Git (like
working with the index) is only available on the command line.
</p>
<p>GPS needs a corresponding <code>diff</code> command that usually comes with it.
</p>
</dd>
<dt><b>Subversion</b></dt>
<dd><a name="index-VCS_002c-Subversion"></a>
<p>The Subversion version control system. Note that on Windows this
version is intended to be used with Cygwin/Subversion and fully supports the
Cygwin path names.
</p>
<p>GPS needs a corresponding <code>patch</code> and <code>diff</code> command
that usually comes with it.
</p>
</dd>
<dt><b>Subversion Windows</b></dt>
<dd><a name="index-VCS_002c-Subversion-Windows"></a>
<p>The Windows native Subversion version control system. The external
Subversion commands are expected to be built for the Win32
subsystem. This version does not support Cygwin path names.
</p>
<p>GPS needs a corresponding <code>patch</code> and <code>diff</code> command
that usually comes with it.
</p></dd>
</dl>
<p>The default VCS that GPS will use is "Auto" by default, and this can be
configured through <a href="The-Preferences-Dialog.html#The-Preferences-Dialog">The Preferences Dialog</a>.
</p>
<p>It is also possible to add your own support for other version control systems,
or modify one of the existing interfaces, see
<a href="Adding-support-for-new-Version-Control-Systems.html#Adding-support-for-new-Version-Control-Systems">Adding support for new Version Control Systems</a> for more information.
</p>
<p>It is recommended that you first get familiar with the version control
system that you intend to use in GPS first, since many concepts used in GPS
assume basic knowledge of the underlying system.
</p>
<p>Associating a VCS to a project enables the use of basic VCS features on the
source files contained in the project. Those basic features typically include
the checking in and out of files, the querying of file status, file revision
history, comparison between various revisions, and so on.
</p>
<a name="index-password-1"></a>
<p>Note: the set-up must make sure that the VCS commands can be launched without
entering a password.
