    <h2 id="overview">Overview</h2>
    <p>
      C-Pluff is a plug-in framework for C programs.
      It has been strongly inspired by the Java plug-in framework in
      <a href="http://www.eclipse.org/">Eclipse</a>. C-Pluff focuses on
      providing core services for plug-in interaction and plug-in
      management. It aims to be platform neutral and supports dynamic
      changes to plug-in configuration without stopping the whole
      application or framework. It does not yet provide special facilities
      for distribution such as signed plug-in packages or remote plug-in
      repositories but it is possible to build such features on top of the
      current framework.
    </p>
    <p>
      The current C-Pluff implementation and documentation is very much
      work in progress so it should be considered early alpha stage software.
      I will be updating the documentation and source distribution on this
      site as I proceed with documentation and implementation.
      If you are interested in C-Pluff, take a look at
      <a href="reference/c-api/index.html">reference documentation</a>,
      join <a href="http://www.c-pluff.org/lists">mailing lists</a> or
      <a href="http://www.c-pluff.org/download">download it</a>. You can also send
      feedback, ideas and thoughts about such platform directly to the
      <a href="mailto:johannes.lehtinen@iki.fi">author</a>.
    </p>
    
    <h2 id="structure">Architecture</h2>
    <p>
      The plug-in architecture supported by C-Pluff is presented in the
      following figure. There is a thin main program controlling the plug-in
      framework. The main program is responsible for initializing and setting
      up the plug-in environment. Most of the application logic is contained in
      plug-ins which are independent components and can be developed and
      distributed separately. Plug-ins integrate with each other by providing
      extension points and extensions. An extension point is a point into which
      other plug-ins can attach extensions. An extension can be just
      information, expressed in XML format, or the plug-in may also provide
      program logic as part of the plug-in runtime library. The framework
      provides services for accessing extensions and for managing plug-in
      dependencies.
