Batch Conversion of PNGs to PDFs

Some quick shell scripts (sh and csh) to convert all the PNG files in a directory to PDF files. The command for conversion was found on Mac OS X Hints. The difference between the two is how variables are set and the loop syntax.

for file in *.png

   echo "Converting $file"

      #  check basename

      #  convert file using basename
