# <synopsis>

# imhead_test.py is a Python script that tests the correctness

# of the imhead task in CASA.  This is essentially a unit test

# for the imhead task.

#

# However, it is also used as a regression test for the imhead task.

#

# </synopsis> 

#

# <example>

# # This test was designed to run using the CASA unit test system.

# # This example shows who to run it manually from within casapy.

# runUnitTest.main(['test_imhead'])

#

# or outside casapy like this:

# casapy -c runUnitTest.py test_imhead

#

# </example>

#

# <motivation>

# To provide a test standard to the imhead task to try and ensure

# coding changes do not break the 

# </motivation>

#

# <todo>

#  1. produce summary data

#  2 make sure failure_msgs is used everywere, and display them#

# </todo>
