# NAME:
#	login_csh
# PURPOSE:
#	Sets up common environment for all user accounts.
# CALLING SEQUENCE:
#	This script is probably best added to the global startup
#	file /etc/csh.login as:
#
#	source /full_dir/login_csh smei_account smei_dir dat_dir temp_dir ssw_dir sswdb_dir
#
#	full_dir	full directory path to this script
#	smei_account	username of SMEI software account
#	smei_dir	directory assigned to env var $SMEI
#	dat_dir		directory assigned to env var $dat
#	temp_dir	directory assigned to global temp dir
#			(will usually be replaced by directory in users
#			home directory)
#	ssw_dir		directory assigned to SSW tree
#	sswdb_dir	directory assigned to SSWDB data base directory
# OUTPUTS:
#	Several other env variables are defined to navigate the SMEI
#	software tree: $COM, $EXE, $HTM
#
#	Equivalent env variables are set up to navigate a
#	personal software tree: $EXE
#
#	Defines IDL_STARTUP=$pro/idl_startup.pro
#
#	If the directory $HOME/soft does not exist, it is assumed
#	that a new user account is accessed for the first time and
#	a few initializations occur:
#	- the directory $HOME/soft is created with in it
#	  the subdirectories $myfor, etc.
#	- the file ~/LOGFIL.TXT is initialized
#	- the startup file $HOME/.bash_profile is modified by
#	  adding $EXE and $COM to the path.
# CALLS:
#	newaccount, alias_csh, update_logfile
# PROCEDURE:
#	The call to this script should be the only place
#	where directories need to be hardcoded.
# MODIFICATION HISTORY:
#	FEB-2001, Paul Hick (UCSD/CASS)
#	AUG-2002, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
#		Introduced command line arguments to set env variables
#		instead of hardcoding them for each Linux box separately.
#-

# $EXE and $COM should be added to the path.
# $EXE contains binary executable
# $COM contains scripts called directly
# $TEMP is temporary directory (different for each user)
