#   pdf2tiff
#
#     Rasterizes a PDF file, saving as a set of g4 compressed tiff images
#
#     input:  PDF
#             root name of output files
#     output: g4 compressed tiff binary files for each page
#
#  Note 1:  Requires ghostscript
#
#  Note 2:  A modern alternative to ghostcript is to use poplar:
#    If the pdf is composed of images that were orthographically generated:
#          pdftoppm -png <pdf-file> <pdf-root>    [output in png]
#    If the pdf is composed of images that were scanned:
#          pdftoppm -jpeg <pdf-file> <pdf-root>   [output in jpeg]
