# NAME
#	version.sh - determine OpenSDE version information 
#
# SYNOPSIS
# 	version.sh [-fp]
# 
# DESCRIPTION
#	The version.sh script determines OpenSDE version informations
#	by first checking if dedicated VERSION files for the OpenSDE
#	framework and the package tree do exist, for extracting the
#	version strings out of the files. In the case a VERSION file
#	does not exist or if it extracts an empty version string from
#	the an existing VERSION file it will assign a default version. 
#
#	If the version strings of the framework and the package tree
#	are not the same the returned version string will be composed
#	out of framework and the package tree version strings delimited
#	by an '-'. Otherwise it will only return the framework version
#	string.
#		
# OPTIONS
#	-f
#		only return the version of the OpenSDE framework
#	-p
#		only return the version of the OpenSDE package tree
#
