 # This include file <doc.images.mk> handles image processing.
 #
 # There are two types of images that must be handled:
 #
 #  1.  Images from the library directory, that are shared across multiple
 #      documents.
 #
 #  2.  Images that are document specific.
 #
-# For library images this file ensures that they are copied in to the 
+# For library images this file ensures that they are copied in to the
 # documents directory so that they can be reference properly.
 #
 # For library images *and* document specific images, this file ensures
 # that the images are converted from their repository format to the
 # correct output format.
 #
 
 #
 # Using document specific images
 # ------------------------------
 #
 # The images that each document provides *from the repository* are listed in
 # the IMAGES variable.
 #
 # We then need to build a list of images that must be generated from these.
 # This is to handle the case where a document might include some images as
 # bitmaps and some as vector images in the repository, but where, depending
 # on the output format, you want all the images in one format or another.
 #
 # This list of generated images can then be cleaned in the clean target
 # later
 #
 # This is the same for each format.  To use IMAGES_GEN_PNG as an example,
 # the substitution means "First match, using M, all the components of
 # ${IMAGES} that match the '*.eps' regexp.  Then, search/replace the .eps
 # in the matching filenames with .png.  Finally, stick the results in the
 # ${IMAGES_GEN_PNG} variable."  ${IMAGES_GEN_PNG} then contains the names
 # of all the .eps images listed, but with a .png extension.  This is the
 # list of files we need to generate if we need PNG format images.
 #
 # The PDF generation, when it's looking for file 'foo', will first try
 # foo.pdf, and it will try foo.png.  There's no point converting PNG files
 # to PDF, as they'll be used directly.  However, we can convert the EPS files
 # to PDF, and hopefully get better quality.
