PHP code XML equivalent 
           
$p2->resetUsestask();
// use channel-based package
$p2->addUsestask('foo',
    'Task_Foo', 'pear.example.com');
           
          

           
<usestask>
 <task>foo</task>
 <package>Task_Foo</package>
 <channel>pear.example.com</channel>
</usestask>
           
          

           
$p2->resetUsestask();
// use uri-based package
$p2->addUsestask('foo',
    'http://pear.example.com/Task_Foo-0.1.0');
           
          

           
<usestask>
 <task>foo</task>
 <package>Task_Foo</package>
 <uri>http://pear.example.com/Task_Foo-0.1.0</uri>
</usestask>
