#!/bin/bash
# .login

#+
# NAME:
#	login
# PURPOSE:
#	Sets up common environment for all user accounts.
# CALLING SEQUENCE:
#	This script is probably best added to the global startup
#	file /etc/bashrc as:
#
#	. /full_dir/login smei_account smei_dir dat_dir ssw_dir sswdb_dir
#
#	full_dir	full directory path to this script
#	smei_account	the user name of the SMEI software account
#			(default: soft)
#	smei_dir	directory assigned to env var $SMEI
#			(default: /home/soft/smei)
#	dat_dir		directory assigned to env var $DAT
#			(default: undefined)
#	ssw_dir		directory assigned to SSW tree
#			(default: undefined)
#	sswdb_dir	directory assigned to SSWDB data base directory
#			(default: undefined)
# 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: $FOR, $EXE, $PRO, $COM
#
#	Defines IDL_STARTUP=$SMEI/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 $for, 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_bash, update_logfile, intel_setup
#	mkramdisk
# 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)
#		Introduced command line arguments to set env variables
#		instead of hardcoding them for each Linux box separately.
#	JAN-2003, Paul Hick (UCSD/CASS)
#		Added env var PYTHONPATH
#	JUN-2003, Paul Hick (UCSD/CASS)
#		Added env vars SMEIDB, SMEIDB1, SMEIDB2, SMEIDB3
#	FEB-2004, Paul Hick (UCSD/CASS; pphick@ucsd.edu)
#		Added env var for CVS depository
#		Added experimental setup for running ssh-agent2
#       JUN-2006, Zachary Vaughan (UCSD/CASS; vaughan.zachary@gmail.com
#               Added argument for java home directory
#	JUN-2006, Java is now set up by sourcing script java_setup.
#		Java-related aliases have been added to alias_bash.
#-

# $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)
