This program will remove an entire directory tree from a hard
drive. BE VERY CAREFULL. It is very easy to accidently delete
the entire contents of the hard drive.
Program syntax is:
rmtree [-l log_file] dirpath
Where 'log_file' is the name of an optional log_file. The log at
this point is very verbose (program uses the 'logman' API for logging),
and 'dirpath' is the absolute path to the directory you want to
delete. Program returns zero upon success, one otherwise. Program
uses the 'armtree' API to perform the deletion of the directory tree.

Ported to QNX, 32bit Windows and DOS. Jun/2005, Rick Smereka */
