"""
This is a script that executes a number of tests on servers defined in
a file of servers to test the characteristics of the servers themselves
and the pybem algorithms for the get_central_instances() method. It
gets the servers for which tests are to be executed from a file, allows the
user to select particular servers, and then executes all of the defined tests
and display methods or just those selected on the command line.

Output is sent to stdout.

It is not publically supported but to be used as apywbem project internal test
tool.

NOTE: Since this is a development support tool, in includes an import that
is not part of the pywbem install imports (tabulate).  This package must
be manually  imported for this script to execute correctly
