[sane-devel] help with getting scanbd and interactive scanner tools working together

[Ron Young]

Apologies, I sent the wrong notes for the saned only configuration 
notes, new files are attached.

Also, what doesn't work in the scanbd configuration is that the sane 
tools/gscan2pdf/simple-scan doesn't see the scanner.
