 An example of how to use the `Tracking_Allocator` to track subsequent allocations
 in your program and report leaks and bad frees:
 
-```odin
-package foo
-
-import "core:mem"
-import "core:fmt"
-
-_main :: proc() {
-	do stuff
-}
-
-main :: proc() {
-	track: mem.Tracking_Allocator
-	mem.tracking_allocator_init(&track, context.allocator)
-	defer mem.tracking_allocator_destroy(&track)
-	context.allocator = mem.tracking_allocator(&track)
-
-	_main()
-
-	for _, leak in track.allocation_map {
-		fmt.printf("%v leaked %m\n", leak.location, leak.size)
+Example:
+	package foo
+	
+	import "core:mem"
