+%%% Description:
+%%% 
+%%%
+%%% The suites used for the test are located in the data directory.
+%%%
+%%% The group(s) and case(s) are specified according to this:
+%%%
+%%% Tests = ct_groups:find_groups(Mod, GroupPaths, TestCases, GroupDef)
+%%%
+%%% GroupPaths = GroupPath | [GroupPath]
+%%% GroupPath = atom() | [atom()]
+%%%
+%%% CT will find all paths that include GroupPath. GroupPath can be a
+%%% single group, or a list of groups along the path to TestCases.
+%%% If GroupPath is the latter, the last group in the list must be
+%%% the "terminating" group in the path, or it will be impossible to
+%%% execute test cases in higher level groups *only*, as in this case:
+%%% groups() -> [{g1,[],[tc1,{g2,[],[tc2]}]}].
+%%% Compare: find_groups(x, g1, all, groups()), and
+%%%          find_groups(x, [[g1]], all, groups())
+%%%
+%%% Some examples:
+%%%
+%%% GroupPaths = g1, means find all paths with g1 included
+%%% GroupPaths = [g1], -''-
+%%% GroupPaths = [g1,g2], search twice - once for g1 and once for g2
+%%% GroupPaths = [[g1,g2]], find cases under group g1 and sub group g2
+%%% GroupPaths = [[g1,g2],[g1,g3]], find cases for g1-g2 AND g1-g3
+%%%
+%%% TestCases = all | atom() | [atom()]
