Well... There you name it ;)

For a bigger scan job, I wrote a small script, which translates our 
institute's scanner output format (JBIG) into something more common -- 
with scaling, page rotation, margin cutting, and final conversion to PDF 
via JPG.

If you have Cygwin installed (plus pnmutils and ImageMagick, the jbigkit 
probably isn't required if your scanner does not also output this 
format), the following might also work for you:

#!/bin/bash
i=$1 ; 
while [ $i -le $2 ] ; 
	do echo $i ; 
	jbgtopbm $i.jbg | \
	pnmscale 0.25 | \
	pnmcut -left $3 -right $4 -top $5 -bottom $6 | \
	pnmscale 0.25 | \
	pnmflip -r90 | \
	pnmtojpeg --greyscale --smooth 10 | \ 
	convert - $i.pdf ; 
	let i=$i+1 ; 
done ;

Final assembly of individual PDF files into a single document can be 
easily done with pdftk.
