<h1>Welcome to Apache Axis2/C</h1>
<p>Axis2/C is an effort to implement <a
href="http://ws.apache.org/axis2/1_0/Axis2ArchitectureGuide.html">Axis2
architecture</a>, in C. Axis2/C can be used to provide and consume Web
Services.</p>
<h2>Background and Motivation</h2>
<p>Axis 2 Java team released 1.0 recently. This implementation provides
another language option to consume and provide Web Services. Performance
being its forte, Axis2/C is looking at broadening its horizon by providing
extensions to popular open source scripting languages and web browsers.</p>
