## convert Casio *.CAM files to JPEGS
## cam files were generated by the Casio QV-10a <http://www.casio-usa.com/products/archive/Cameras/QV_Series/QV-10A/>
## this script uses command-line code from <http://www.linuxjournal.com/article/2664>
## this script requires camtoppm.pl from <http://www.asahi-net.or.jp/~xg2k-hys/index-e.html>

## PROCESS ##
# loops through each file passed in
# converts using camtoppm.pl, djpeg, pnmscale, cjpeg
# saves as originalfilename.newextension (.jpg)

## REQUIREMENTS ##
# perl MUST BE installed
# camtoppm.pl MUST BE in same directory as this script

echo "$# arguments sent to $0" # N arguments sent to /this/scripts/path
