This information is built-in to the Debug Console (which is based on
code from the Palm Debugger application). Neither one is extensible
in terms of providing your own ability to provide chunk information.
Most of the chunks that Palm OS(TM) knows about are labeled for you,
which should leave very few "unknown" chunks. The unlabeled chunks
are almost always chunks that have been allocated (directly or
indirectly) by your application.
