Welcome to Explode!

Explode is a small directory tree view utility for the Atari ST series
desktop computers and its offspring.

It can be used as a prg on multitasking environments or as a
accessory on single TOS. For use as a accessory, change suffix to ACC
and put the program in your boot drive. Then reboot.

On single TOS starting programs may not work, but I tested with Teradesk
and opening directories and files for the viewer worked.

Explode tries to locate a AV server which would mostly be a desktop
program. When a AV server is net yet loaded, Explode tries 5 times
with a 1 second interval. When a AV server can not be found,
Explode displays a alert box in which you can choose between
Quit, Retry or Without.
Without AV server Explode is still a useful directory display routine.

If the environment variable AVSERVER is absent, Explode first
tries to find "DESKTOP ", then tries to find "MAGXDESK".

A nice aspect of Explode is that it always keeps its window as small
as possible exposing as much precious screen area as possible without
special action.

Explode defaults its window position to the lower right corner of the
sreen until the user has moved the window. This new position will be
used as the return position from then on.

Explode understands the AP_TERM message.

Mouse usage
===========
left click:	explode or collapse directory.
right click:	Directory: Send AV_OPENWIND to AV server.
			   Teradesk opens a directory window.
		File:      Send AV_STARPROG to AV server.
			   Teradesk performs expected action on the file
			   based on its type or extension.

Drag and drop:	Depends totally on the AV server implementation and the
		receiver of the drop.
		Drag on a window or the desktop background sends
		AV_DRAG_ON_WINDOW to the server if there is one.
		All other cases a standard DRAG&DROP protocoll is started.
		I discovered that Teradesk converts a AV_DRAG_ON_WINDOW
		message to a DRAG&DROP protocoll if a drop is on a window
		not owned by Teradesk. Which is nice :-)

Keyboard usage
==============
Ctrl+Q, Ctrl+U	Program:   Quit
		Accessory: Collapse all and close window.
ESC		Collapse all.

Cursor right	Explode directory and go to first sibling.
Curser left	Collapse directory.
Cursor down	Go to next line.
			With only 3 fingers you can go quickly through
			all the drives and directories of your system.
Cursor up	Go to prvious line.

Shift + cursor right	Go to next of parent directory.
Shift + cursor left	Go to parent directory.

Shift cursor down	Go half a page down.
Shift cursor up		Go half a page up.

INS, UNDO		explode or callapse directory.

Explode comes in 2 flavours:
explode.acc		a 68000 version
explode.prg		a Coldfire/68020 version

You can choose the processor version you need, move it to its
destination and then change its suffix to the one you need.

Have fun!
