ProjectHelper Task

## ProjectHelper

### Description

This task is provided for the purpose of allowing the user to install a different ProjectHelper at runtime.

The helpers will be added after all the already registered helpers, but before the default one (ProjectHelper2)

See the description of Apache Ant's Project Helper for more information.

Since Ant 1.8.2

### Parameters specified as nested elements

You may specify many configured `org.apache.tools.ant.ProjectHelper` instances.

### Example

Install a custom ProjectHelper implementation (assuming `MyProjectHelper extends ProjectHelper`):

    <typedef classname="org.example.MyProjectHelper"
                  name="myprojecthelper"/>
    <projecthelper>
      <myprojecthelper/>
    </projecthelper>
