  * I didn't implement mm_checkheap. It was more convinient for me to implement
  * separate functions for printing and checking integrity of the heap and data
- * structures. All those functions are run only if the DEBUG flags is defined,
- * otherwise their body is empty. I also used sanitzer. What I checked in those
- * debug functions:
+ * structures. All those functions are run only if the DASSERT flags is defined.
+ * There is debug ouput only if both DASSERT and DEBUG flags are defined. 
+ * I also used sanitzer. What I checked in those debug functions:
  *
  * - Integrity of the heap, i.e. check if there are no adjacent free blocks,
  *   check if prevfree bits are set correctly, check if last block is actually
  *   the last block, check if last block ends with the heap.
  * - Integrity of the free block list, if the size in both boundary tags are
- *   equal, if none of them has the prevfree block set
+ *   equal, if none of them has the prevfree block set etc.
+ * 
+ * There are also many assert in other functions. They also serve as a hint
+ * about assumptions the function has (e.g. argument points to a free block).
