Jpegs to djvu

Bash script for converting all jpeg files in a folder into a single djvu file:

#!/bin/bash
#
for i in *.JPG; do 
  echo $i; 
  c44 -size 5000,250000 $i $i.djvu; 
done; 
djvm -c out.djvu *.JPG.djvu; 
rm *.JPG.djvu

c44 size parameter affects quality. 250Kb suits me well. c44 and djvm are in package djvulibre-bin.
