# check_ndd: checks for security configuration parameters of the
#            network environment (using ndd)
#            This modules provides generic support routines for the ndd
#            checks, allowing for better sharing of code between HP-UX,
#            Solaris, and potentialy other Unixes.
#
# 07/11/2003 rbradetich@uswest.net - Initial version. 
#
# 05/02/2004 jfs  Try to avoid eval problems if handling variables with
#                 special characters (such as space)
# 08/09/2003 jfs - Placed in the generic default directory for Unix systems
#            so that systems can run them using 'check'

# Several of the help entries for these ndd commands were pulled
