%% Verify that Mnesia really is a distributed real-time DBMS.
%% This is the test suite of the Mnesia DBMS. The test suite
%% covers many aspects of usage and is indended to be developed
%% incrementally. The test suite is divided into a hierarchy of test
%% suites where the leafs actually implements the test cases.
%% The intention of each test case and sub test suite can be
%% read in comments where they are implemented or in worst cases
%% from their long mnemonic names. 
%% 
%% The most simple test case of them all is called 'silly'
%% and is useful to run now and then, e.g. when some new fatal
%% bug has been introduced. It may be run even if Mnesia is in
%% such a bad shape that the test machinery cannot be used.
%% NB! Invoke the function directly with mnesia_SUITE:silly()
%% and do not involve the normal test machinery.
