ProjectHelper Task

## ProjectHelper

Since Ant 1.8.2

### Description

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

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.

### 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>
