+    Title: Assert
+
+    About: Purpose
+        Definition of the ASSERT() macro, which is used for runtime condition
+        verifying.
+
+    About: Usage
+        1 - Use <ASSERT> in your code to check the value of function parameters,
+            return values, etc. *Warning:* the ASSERT condition must not have
+            any side-effect; otherwise, the program may not work properly
+            anymore when assertions are disabled.
+        2 - Use SANITY_CHECK to perform checks with a default error message
+            (outputs the file and line number where the error occured). This 
+            reduces memory overhead caused by assertion error strings.
+        3 - Initialize the <DBGU> to see failed assertions at run-time.
+        4 - Disable assertions by defining the NOASSERT symbol at compilation
+            time.
