-# check_sig_type() #
-# Usage: check_signal [ -{signal} | {signal} ] #
-# #
-# Purpose: Check if signal is a program termination signal or a control signal #
-# This is not defined by any LSB draft, however, it is required to #
-# check the signals to determine if they are intended to end a #
-# program or simply to control it. #
-# #
-# Inputs: Accepts a single string value in the form or -{signal} or {signal} #
-# #
-# Return values: #
-# 0 - Signal is used for program termination #
-# 1 - Signal is used for program control #
