+@findex srunner_tap_fname
+The log can also be written in TAP.  The following functions define
+the interface for TAP logs:
+@example
+@verbatim
+void srunner_set_tap (SRunner *sr, const char *fname);
+int srunner_has_tap (SRunner *sr);
+const char *srunner_tap_fname (SRunner *sr);
+@end verbatim
+@end example
+
+TAP output is enabled by a call to @code{srunner_set_tap()} before the tests
+are run. Here is an example of an TAP log:
+@example
+@verbatim
+ok 1
+ok 2
+not ok 3
+ok 4
+1..4
+@end verbatim
+@end example
+
+TAP logging can be enabled by an environment variable as well. If
+@code{CK_TAP_LOG_FILE_NAME} environment variable is set, the TAP test log will
+be written to specified file name. If TAP log file is specified with both
+@code{CK_TAP_LOG_FILE_NAME} and @code{srunner_set_tap()}, the name provided
+to @code{srunner_set_tap()} will be used.
+
+If both plain text and TAP log files are specified, by any of above methods,
+then check will log to both files. In other words logging in plain text and TAP
+format simultaneously is supported.
