/**
* 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.
