+/* Check: a unit test framework for C
+
+   Check is a unit test framework for C. It features a simple
+   interface for defining unit tests, putting little in the way of the
+   developer. Tests are run in a separate address space, so Check can
+   catch both assertion failures and code errors that cause
+   segmentation faults or other signals. The output from unit tests
+   can be used within source code editors and IDEs.
+
+   Unit tests are created with the START_TEST/END_TEST macro
+   pair. The fail_unless and fail macros are used for creating
+   checks within unit tests; the mark_point macro is useful for
+   trapping the location of signals and/or early exits.
+
+
+   Test cases are created with tcase_create, unit tests are added
+   with tcase_add_test
+
+
+   Suites are created with suite_create; test cases are added
+   with suite_add_tcase
+
+   Suites are run through an SRunner, which is created with
+   srunner_create. Additional suites can be added to an SRunner with
+   srunner_add_suite. An SRunner is freed with srunner_free, which also
+   frees all suites added to the runner. 
+
+   Use srunner_run_all to run a suite and print results.
+
+   Macros and functions starting with _ (underscore) are internal and
+   may change without notice. You have been warned!.

+ * - The fork() call has the effect of duplicating the file descriptor
+ *   and copying (on write) the FILE* data structures.
+ * - The child writes to the file, and its dup'ed file descriptor and
+ *   data structures are cleaned up on child process exit.
+ * - Before reading, the parent rewind()'s the file to reset both
+ *   FILE* and underlying file descriptor location data.
+ * - When finished, the parent fclose()'s the FILE*, deleting the
+ *   temporary file, per tmpfile()'s semantics.
+ *
+ * This scheme may break down if the usage changes to asynchronous
