-#!/bin/sh
-#
-# usage: casa-script <script.py> [script arguments...]
-#
-# Credit: https://github.com/pkgw/pwpy - intfbin/casa-script
-# License: GPLv3+
-#
-# This tool makes it possible to run scripts in a full CASA environment from
-# the command line in the sanest way I can muster (for my personal definition
-# of "sane"). Expected usage is in a hashbang line in the script:
-#
-# #! /usr/bin/env casa-script
-# # -*- python -*-
-# ...
-#
-# The elements of sanity are:
-#
-# - casapy is invoked in a temporary directory, so that the logfile turds it
-# likes to drop everywhere get cleaned up.
-# - command-line arguments are made accessible to the script in a clean-ish
-# way (last I checked, this didn't work with straight-up casapy)
-# - output is redirected so that casapy's incessant chatter can be silenced
-# - the GUI is disabled
-#
-# Unfortunately I am unable to do anything about casapy's terrible startup
-# time.
-#
-# Inside the temporary directory, the invocation directory of this script is
-# symlinked under the name 'data'. All file paths should begin with 'data/',
-# with special care for command-line arguments, which will need post-processing.
-#
-# The command-line arguments to the invoked script are saved, separated by
-# **NULs**, in a file in the temporary directory called 'args'. These can be
-# retrieved with:
-#
-# argv = open ('args').read ().split ('\0')[2:-1]
-# # or
-# args = open ('args').read ().split ('\0')[3:-1]
-#
-# The output of casapy is redirected to files 'stdout' and 'stderr' in the
-# temporary working directory. The standard output and error of this script
-# are linked to FIFOs in the work directory named 'csout' and 'cserr'.
-# Therefore, to selectively output data to the invoker, do
-#
-# csout, cserr = open ('csout', 'w', 1), open ('cserr', 'w', 1)
-# ...
-# print >>csout, 'info: this script works'
-# ...
-# print >>cserr, 'warning: your data are broken'
-#
-# Keep in mind that the script is being executed in CASA's IPython
-# environment, so the environment is highly non-vanilla. Because IPython
-# just prints exceptions to the screen, you need to wrap the entire program
-# in a try/except block and handle them manually:
-#
-# # after setting up cserr
-# try:
-# ... entire program ...
-# except SystemExit:
-# pass
-# except:
-# import os, sys, traceback
-# traceback.print_exception (*sys.exc_info (), file=cserr)
-# os._exit (1)
-#
-# Note that we need to use os._exit() to be able to actually exit with an
-# error return code. Do not use sys.exit() or (CASA's) exit().
-
-# Set up a fully-qualified path name to the input script so that CASA can
-# always find it, even when we hop around in subdirectories. Otherwise it
-# tries to evaluate the filename as a line of Python.
-
-script=$(cd $(dirname $1) && pwd)/$(basename $1)
-if [ ! -e "$script" ] ; then

-# http://stackoverflow.com/a/1645157/3760486 I'm sure I could do a
