	How to use FabSim3 singularity image :)

	USAGE:
		./fabsim.simg [option]

	OPTIONS:
		-h|--help				print container help
		-i|--install [PATH]     install fabsim3 in in your local machine
					by default, it will be downloaded in sub-folder ./FabSim3 in your current directory
					you also can set the installation directory by setting PATH parameter

EOF_HELP

	#-----------------------------------------------------------------
	#				 fabsim_env.conf
	#
	cat << EOF_FabSim_ENV > /fabsim_container_files/fabsim_env.conf
	
	#export PYTHONPATH=\${fabsim_INSTALL_DIR}:\$PYTHONPATH
	export fabsim_INSTALL_DIR=\${fabsim_INSTALL_DIR}
	alias fab="\$PWD/fabsim.simg"

EOF_FabSim_ENV

	#-----------------------------------------------------------------
	#				make the setup_fabsim_env file	
	#
	cat << EOF_setup_fabsim_env > /fabsim_container_files/setup_fabsim_env

	please add/load the generated fabsim_env.conf in your ~/.bashrc

		To load: 
				$ source \${fabsim_INSTALL_DIR}/fabsim_env.conf

		To add to your ~/.bashrc
				$ echo \"source \${fabsim_INSTALL_DIR}/fabsim_env.conf\" >> ~/.bashrc
				$ source ~/.bashrc

EOF_setup_fabsim_env

	#-----------------------------------------------------------------
	#				fabsim_env_warning	
	#
	cat << EOF_fabsim_env_warning > /fabsim_container_files/fabsim_env_warning

	environment variable \$fabsim_INSTALL_DIR is empty !!!

	1)	Please make sure you install fabsim by
			$ ./fabsim.simg -i [preferred install directory]
			or
			$ ./fabsim.simg --install [preferred install directory]

	OR

	2)	if you did the previous step, 
		please go <fabsim_INSTALL_DIR> and add/load the generated fabsim_env.conf in your ~/.bashrc
		
		To load: 
				$ source <fabsim_INSTALL_DIR>/fabsim_env.conf

		To add to your ~/.bashrc
				$ echo "source <fabsim_INSTALL_DIR>/fabsim_env.conf" >> ~/.bashrc
				$ source ~/.bashrc

	NOTE:	In all cases, <fabsim_INSTALL_DIR> should be replaced 
		by your local fabsim installation directory
