/** @defgroup grp_rt_assert     Assert - Assertions
 * @ingroup grp_rt
 *
 * Assertions are generally used to check preconditions and other
 * assumptions. Sometimes it is also used to catch odd errors or errors
 * that one would like to inspect in the debugger. They should not be
 * used for errors that happen frequently.
 *
 * IPRT provides a host of assertion macros, so many that it can be a bit
 * overwhelming at first. Don't despair, there is a system (surprise).
 *
 * First there are four families of assertions:
 *      - Assert        - The normal strict build only assertions.
 *      - AssertLogRel  - Calls LogRel() in non-strict builds, otherwise like Assert.
 *      - AssertRelease - Triggers in all builds.
 *      - AssertFatal   - Triggers in all builds and cannot be continued.
 *
 * Then there are variations wrt to argument list and behavior on failure:
 *      - Msg           - Custom RTStrPrintf-like message with the assertion message.
 *      - Return        - Return the specific rc on failure.
 *      - ReturnVoid    - Return (void) on failure.
 *      - Break         - Break (out of switch/loop) on failure.
 *      - Stmt          - Execute the specified statement(s) on failure.
 *      - RC            - Assert RT_SUCCESS.
 *      - RCSuccess     - Assert VINF_SUCCESS.
 *
 * In addition there is a very special family AssertCompile that can be
 * used for some limited compile-time checking, like structure sizes and member
 * alignment. This family doesn't have the same variations.
 *
 *
 * @remarks As you might have noticed, the macros don't follow the
 * coding guidelines wrt to macros supposedly being all uppercase
 * and underscored. For various  reasons they don't, and nobody
 * has complained yet. Wonder why... :-)
 *
 * @remarks Each project has its own specific guidelines on how to use
 * assertions, so the above is just trying to give you the general idea
 * from the IPRT point of view.
