<a name="WhatisVelocity?"></a>
<h1>What is Velocity?</h1>
<div class="subsection">
<p> Velocity is a Java-based template engine. It permits anyone to use a simple yet
powerful template language to reference objects defined in Java code. </p>
<p> When Velocity is used for web development, Web designers can work in parallel with
Java programmers to develop web sites according to the Model-View-Controller (MVC)
model, meaning that web page designers can focus solely on creating a site that looks
good, and programmers can focus solely on writing top-notch code. Velocity
separates Java code from the web pages, making the web site more maintainable over its
lifespan and providing a viable alternative to
<a href="http://java.sun.com/products/jsp/">Java Server Pages</a> (JSPs) or
<a href="http://www.php.net/">PHP</a>. </p>
<p> Velocity's capabilities reach well beyond the realm of the web; for example, it can
be used to generate SQL, PostScript and XML (see
<a href="anakia.html">Anakia</a> for more information on XML
transformations) from templates. It can be used either as a standalone utility for
generating source code and reports, or as an integrated component of other systems.
For instance, Velocity provides template services for the
<a href="http://jakarta.apache.org/turbine/">Turbine</a> web application
framework, together resulting in a view engine facilitating development of web
applications according to a true MVC model. </p>

<a name="WheredoIgetreleases?"></a>
<h1>Where do I get releases?</h1>
<div class="subsection">
<p> The current stable release version is version 1.7. </p>
<p> The release distribution is available as a combined source/binary distribution in
<code>tar.gz</code> and
<code>zip</code> formats, and can be downloaded through the
<a href="http://velocity.apache.org/download.cgi">
Apache Mirror system</a>. </p>
<p> The Velocity jars are also available through the
<a href="http://repo1.maven.org/maven2/org/apache/velocity/">central Maven
repository</a>. </p>
<p> Older releases are archived at the
<a href="http://archive.apache.org/dist/velocity/engine/"> Apache
Velocity archives</a>. </p>
</div>
<a name="WheredoIgetnightlysnapshots?"></a>
<h1>Where do I get nightly snapshots?</h1>
<div class="subsection">
<p> Nightly snapshots of the Velocity subversion source code tree can be found
on our <a href="http://vc.apache.org/snapshots/velocity/">nightly snapshot site</a>. </p>
<p><b>Caveat!</b> These snapshots are generated automatically from the project source code repository. As
this is our live development workspace, there are no guarantees as to what you will
find there, although we do our best to maintain a buildable source tree. If you are
looking for the stable supported release, please use the current release of
Velocity. </p>
<p><b>Please be aware that these snapshots are not official
releases of Apache Velocity software. They are provided for
developer convenience only!</b></p>
<p> If you are willing to risk getting dirty, we invite you to try the nightly snapshot to
see the current state of affairs. (and help out!)
<a href="http://www.apache.org/dev/version-control.html">Public Subversion
access</a> is also available. </p>
