This is implemented as a straightforward Component Plugin, overriding the Administrators action, and using a velocity template for the view. The atlassian-jira.xml descriptor's module is:
<webwork1 key="ASFAdministrators" name="Lists project leads on administrators page" class="java.lang.Object"> <actions> <action name="ASFAdministrators" alias="Administrators"> <view name="success">/templates/asf_administrators.vm</view> </action> </actions> </webwork1>
