+/* glib/C provides the following kind of assertions:
+ *   - assert() -- disable with NDEBUG
+ *   - g_return_if_fail() -- disable with G_DISABLE_CHECKS
+ *   - g_assert() -- disable with G_DISABLE_ASSERT
+ * but they are all enabled by default and usually even production builds have
+ * these kind of assertions enabled. It also means, that disabling assertions
+ * is an untested configuration, and might have bugs.
+ *
+ * Add our own assertion macro nm_assert(), which is disabled by default and must
+ * be explicitly enabled. They are useful for more expensive checks or checks that
+ * depend less on runtime conditions (that is, are generally expected to be true). */
