Jason Tourtelotte (major refinement to the code -- almost a complete rewrite)
Description
This modification adds the ability to show an index listing of pages that start with a certain letter. There is also an alphabetical heading at the top of each listing. Just click a letter to see pages that start with that letter.
For example:
Usage:
{{pageindex letter="d"}}Outcome:
Page Index
This is an alphabetical list of pages you can read on this server.
