# Purpose: Used to check if the pictures (gif files) linked in the manual
# are in their proper places. Creates a web page that contains
# the result of a grep for "gif" in each html file. In most
# cases, this grep provides enough information so the page contains
# simply pictures or "broken picture" icons.
#
# Usage: gif_grep [d1 d2 ...]
#
# If no argument is given, the default is to grep all html files
# in the current directory and all subdirectories. Otherwise,
# only the html files in subdirectories given as arguments are
# searched.
