Need:"awk" references & indexing utility source

[David P Huelsbeck]

	I've been using "awk" extensively of late, and I've exhausted my
available reference material. Does anyone know of a reference on awk that
goes beyond what can be found in K&P and _Unix Programmer's Manual_ ?

	Also, does anyone have the source code for a utility for creating
indexes for UNIX text files? 

Thanks in advance.
