- * Module for heap-profiling.
- *
- * For full(er) information, see doc/heapprofile.html
- *
- * This module can be linked into your program with
- * no slowdown caused by this unless you activate the profiler
- * using one of the following methods:
- *
- *    1. Before starting the program, set the environment variable
- *       "HEAPPROFILE" to be the name of the file to which the profile
- *       data should be written.
- *
- *    2. Programmatically, start and stop the profiler using the
- *       routines "HeapProfilerStart(filename)" and "HeapProfilerStop()".
