00010  *   MorePalmOS is the humble begining of an attempt to provide a library for
00011  *   Palm OS development which works around system bugs, illustrate how to
00012  *   use system calls, and provide "glue code" for programming Palm OS
00013  *   applications in a more straightforward way while minimally impacting
00014  *   code size.
