-This library replaces the C library allocator;
-providing malloc, free, realloc and calloc (sorry, no valloc)
-
-In doing so, it provides extensive memory bug checking, locating:
-
-	Lost memory; memory which has not been freed and which has no
-	references
-
-	In use free memory; memorhy which has been freed and still has
-	references to it.
-
-	Stores to freed memory
-
-	free/realloc with invalid pointers -- if you pass in a pointer to
-	the middle of an allocated block, it will even tell you which one
-
-For each of these errors, a report entry is generated which includes
-the stack backtrace of either the allocation or free (which ever occured
-last) along with the current stack, when relevant.
-
-Unreferenced allocated memory, stores to freed memory and referenced freed
-memory are only caught when CheckMemory is called.  It is automatically
-called each time 1m of data has been freed, and is called when the program
-exits (by registering with atexit(3)/on_exit(3)).  You can call it whenever
-you want.
-
-Both the X server and font servers call CheckMemory after each reset when
-their respective os/utils.c are compiled -DMEMBUG.
-
-There are a few global variables you can set with the debugger to
-help isolate problems:
-
-	FindLeakWarnMiddlePointers
-		Normally, memleak ignores pointers to the middle of
-		freed memory.  These are frequently simply random data
-		which happens to look like a pointer.  Turning this
-		on will generate additional messages.
-	FindLeakAllocBreakpoint
-		At each allocation, memleak increments a serial number
-		and stores it in the allocation header.  By rerunning
-		the program, you can stop when that piece of memory
-		is going to be allocated.  Store the serial number
-		in this global variable and put a debugger breakpoint inside
-		AddActiveBlock at the indicated line.
-	FindLeakFreeBreakpoint
-		Similarly for freeing memory.
-	FindLeakTime
-		The current serial number
-	FindLeakCheckAlways
-		When set, memleak checks the entire memory system after
-		each allocation or free.  This is very expensive, but
-		may catch errors not otherwise found until too late.
-
-To include this in your application, simply place libmemleak.a before the
-end of the link line; it will then override the C library allocator.
-
-To port this system to a new machine, you must provide two values, one
-indicating the lowest data address in a program and one indicating the
-highest stack address.  In addition, to get return stack traces (which are
-almost essential for debugging), you must provide the function
-getReturnStack.  Samples for MIPS and SPARC are included already.
-
-The output from the leak tracer includes only PC values in the stack
-traces.  To convert these into useful values, run the output of
-the leak tracer through the find-routines script; after making sure you have
-built the modified version of gdb-4.4 on your machine.
