/**
 * A task to create PEAR package.xml file.
 * 
 * This class uses the PEAR_PackageFileMaintainer class to perform the work.
 * 
 * This class is designed to be very flexible -- i.e. account for changes to the package.xml w/o
 * requiring changes to this class.  We've accomplished this by having generic <option> and <mapping>
 * nested elements.  All options are set using PEAR_PackageFileMaintainer::setOptions().
 * 
 * The <option> tag is used to set a simple option value.
 * <code>
 * <option name="option_name" value="option_value"/> 
 * or <option name="option_name">option_value</option>
 * </code>
 * 
 * The <mapping> tag represents a complex data type.  You can use nested <element> (and nested <element> with
 * <element> tags) to represent the full complexity of the structure.  Bear in mind that what you are creating
 * will be mapped to an associative array that will be passed in via PEAR_PackageFileMaintainer::setOptions().
 * <code>
 * <mapping name="option_name">
 *  <element key="key_name" value="key_val"/>
 *  <element key="key_name" value="key_val"/>
 * </mapping>
 * </code>
 * 
 * Here's an over-simple example of how this could be used:
 * <code>
 * <pearpkg name="phing" dir="${build.src.dir}" destFile="${build.base.dir}/package.xml">
 *  <fileset>
 *   <include name="**"/>
 *  </fileset>
 *  <option name="notes">Sample release notes here.</option>
 *  <option name="description">Package description</option>
 *  <option name="summary">Short description</option>
 *  <option name="version" value="2.0.0b1"/>
 *  <option name="state" value="beta"/>
 *  <mapping name="maintainers">
 *   <element>
 *    <element key="handle" value="hlellelid"/>
 *    <element key="name" value="Hans"/>
 *    <element key="email" value="hans@xmpl.org"/>
 *    <element key="role" value="lead"/>
 *   </element>
 *  </mapping>
 * </pearpkg>
 * </code>
 *
 * Look at the build.xml in the Phing base directory (assuming you have the full distro / CVS version of Phing) to
 * see a more complete example of how to call this script.
