pct-scanner-script

pct-scanner-script is a bash script (with configuration facility) that drives scanadf, DjVu and PDF tools to create DjVu and PDF output from a scanner.
It's quite clumsy in handling it and does not produce what you want.
Apparently, it does not support OCR! 
$ psct-scanner-script -c --device epkowa:net:192.168.1.102 --source Flatbed -o ~/scanner/output

$ pct-scanner-script --search
-a is a synonym for --search.
