+* This assert abstraction is only used for the flatcc runtime library.
+* The flatcc compiler uses Posix assert routines regardless of how this
+* file is configured.
+*
+* This header makes it possible to use systems where assert is not
+* valid to use. Note that `<assert.h>` may remain a dependency for static
+* assertions.
+*
+* `FLATCC_ASSERT` is designed to handle errors which cannot be ignored
+* and could lead to crash. The portable library may use assertions that
+* are not affected by this macro.
+*
+* `FLATCC_ASSERT` defaults to POSIX assert but can be overrided by a
+* preprocessor definition.
+*
+* Runtime assertions can be entirely disabled by defining
+* `FLATCC_NO_ASSERT`.
