13 * This is an API test for ICU regular expressions in C. It doesn't test very many cases, and doesn't
14 * try to test the full functionality. It just calls each function and verifies that it
15 * works on a basic level.
16 *
17 * More complete testing of regular expression functionality is done with the C++ tests.
