# Name:
# topcat
# Purpose:
# Invokes the TOPCAT application on unix
# Description:
# This shell script invokes the TOPCAT application.
# It's not very complicated, but performs some argument manipulation
# prior to invoking java with the right classpath and classname.
#
# 1. if a class path is specified using either the CLASSPATH
# environment variable or the -classpath flag to this script,
# it will be added to the application classpath
#
# 2. any command-line arguments which look like they are destined
# for java itself (starting with -D or -X, or prefixed with -J) will
# be sent to java, and the others will be sent to the application
# Requisites:
# - java should be on the path.
#
# - relative to the directory in which this script is installed,
# one of the following jar files should exist and contain the
# TOPCAT classes:
# ./topcat-full.jar
# ./topcat-lite.jar
# ../../lib/topcat/topcat.jar
# Authors:
# MBT: Mark Taylor (Starlink)
#-
# Set locations of acceptable jar files (relative to this script).
