Description  -------------------------------------------------
--------------------------------------------------------------

Operation is fairly simple. You move into a directory by
moving the pointer to the directory name and then pressing
the right arrow key. To move up to the parent directory, press
the left arrow key. Pressing Enter will calculate the space
occupied by the directory you are currently in and all files
and directories below your current position. It's easier to
understand by doing it than by me trying to explain it.

If you have a flash disk in one of the drives, PieDir can tell
you how much space is "wasted". "Wasted" space occurs when
a file on a flash disk is deleted. The file disappears, but
the free space on the drive does not increase. The only way to
reclaim the free space is to reformat the drive.

Known bugs  --------------------------------------------------
--------------------------------------------------------------

Scrolling will sometimes leave stray marks in the list. The
marks are from ascenders/descenders which are not completely
erased when scrolling up or down.


--------------------------------------------------------------
Notes  -------------------------------------------------------
--------------------------------------------------------------
The number of clusters a file occupies is not calculated. As a
result, the physical "space" a file uses on the internal drive
can be off by a large margin.

The maximum number of files PieDir can display has been fixed
at 130. 

I developed PieDir using a S3a with 512K memory and a 512K
flash disk.

Unmodified copies of PieDir may be distributed freely. PieDir
may not be distributed with the intent of making a profit
from its distribution. I reserve all rights to PieDir.

Programming tip request: I need at least a "PAUSE 4" in my
main loop in order for auto-turn-off to work. This slows
down the program response. Does anyone know how to get auto-
turn-off to work without using a "PAUSE" command?
