"standard" fret diagrams \include file

[Kieren Richard MacMillan]

Hello, all --

I'm not a guitarist. I'm currently engraving one of my "pop tunes",  
and would like to print a piano-guitar-vocal score with fret diagrams.

I don't want to reinvent the wheel (i.e., by building every fret  
diagram from scratch, using my fake book as a guide) -- does anyone  
have a pre-built set of "standard" fret diagrams that I could use?

Thanks,
Kieren.
