MPIndex is a tool for indexing AmigaGuide documents - similar to the Windows Help Search facility.
MakeMPIndex is used to generate the index.
RunMPIndex can then be used to display a Gui which allows the index to be view and specific nodes selected.
An example usage is:
Find help nodes in all guides except fred.guide which include the words "help" and/or "gadget" in the text and "test" in the title.
