#!/bin/sh -vx
# This is a small sh and awk script to make a Gopher link file from
# a the catalog created by waisindex using the -catalog option. For
# very large databases this link file is uselss, but for small data-
# databases (say 50 or less records) you give the user the option of
# searching or browsing for what they are looking for.
#
# For an example connect to
#
# Name=Brown University Job Openings
# Type=1
# Path=1/brown/departs/hum_res/jobinfo
# Host=gopher.brown.edu
# Port=70
#
# To use this script you need to change the following variables or
# override them on the command line
#
# gopherdir Root directory of the Gopher server
#
# linkdir Directory where the link file should be placed.
# Link is relative to gopherdir.
#
# indexdir Directory where the index files are. The indexdir
# is relative to gopherdir.
#
# index Name of the index file.
#
# title Title for the search link
#
# For example,
#
# ./waisfolder \
# "/nfs/cwis" \
# brown/departs/hum_res/jobinfo \
# usr/hrjobs \
# hrjobs \
# "Search the HR Job Openings"
#
# This script builds a link file suitable for UMN's gopherd server.
# I don't expect it is too difficult to modify it to use someone
# else's WAIS index gopher gateway.
