# Bash shell script to extract bounding box information from a JPEG image
# This makes it possible to use the JPEG image in LaTeX documents.
# The script needs the followin - /bin/awk, /usr/bin/djpeg and
# /usr/bin/pnmtops - which are distributed with most Linux distributions
#
# Usage is as follows : jpgbb graphic.jpg
# This results in a file called graphic.jpg.bb
