    # texinfo files to html using Modern's CSS definitions. We also

    # texi2html's '--I' option. Adding image directories to @include
    # search path is needed in order for texi2html to build html paths
    # correctly, once the html output is produced.  For exmample, if
    # you want to include the following image:
    #
    #   /home/centos/artwork/trunk/Identity/Models/Img/en/Scripts/renderImage.png
    #
    # you add its directory path to @include search path using the
    # following command: 
    #
    #   texi2html --I=/home/centos/artwork/trunk/Identity/Models/Img/en/Scripts
    #
    # Once the image directory path has been added to @include search
    # path, use the @image command inside texinfo files to include
    # images available.  In order to include images correctly, do not
    # include the image path in the first argument of @image command,
    # use just the image name (without extension) instead (e.g.,
    # @image{renderImage,,,,png}).
