#
#   Purpose:  Used to check if the html files contain any backslashes, which
#             often indicates a raw formatting command that didn't get 
#             translated by the cc_manual_to_html program.
#
#   Usage:    backslash_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.
