# Bash shell script to extract bounding box information from a GIFF image
# The script needs the following - /bin/awk, /usr/bin/giftopnm and 
# /usr/bin/pnmtops - which are distributed with most Linux distributions
#
# Usage is as follows : gifbb graphic.gif 
# This results in a file called graphic.gif.bb
