	Glassfish Application Server has been installed using the glassfish
	user and glassfish group.  To use Glassfish as another user, add the
	glassfish group to the user.
	
	To use the Glassfish commands, do 'source /etc/profile'.  This will
	add the ${GLASSFISH_INSTALL_BASE}/bin to your PATH and create the
	GLASSFISH_HOME environment variable as ${GLASSFISH_INSTALL_BASE}.
	
	To get started with Glassfish, see the Quick Start Guide at:
	https://glassfish.dev.java.net/downloads/quickstart/index.html

	If you remove Glassfish, some files may still exist in ${GLASSFISH_INSTALL_BASE}
	from running Glassfish, e.g. log files, new domains, etc.  The removal
	process deliberately leaves these files alone.
