# newwais.pl -- WAIS search interface
#
# from wais.pl
#
# Tony Sanders <sanders@bsdi.com>, Nov 1993
#
# Example configuration (in local.conf):
# map topdir wais.pl &do_wais($top, $path, $query, "database", "title")
#
# this script uses a sneaky feature of Mosaic that interpretes a
# single text input form with the name 'isindex' (case sensitive) to
# the same as a <ISINDEX>. On non-mosaic clients, you wind up with an
# additional query
#
# Note that I know even less about perl than the other two people
# who hacked this, so feel free to send hate mail to pjh@netcom.com
# if I did something really bad (or if there is a better way of
# grabbing the filename off the end of a path.

# parse disc name from ServerName Environt Variable with this script
