ATR Extract version 0.9
-----------------------
This program may be freely distributed but not sold alone or with any other
program for profit.  Original Docs must also the program.  'nuff said, here
goes...


This utility will extract file(s) from an ATR disk image.  To use it
simply use:

ATREXTR atrname.atr filename

filename is the filename of a file on the ATR.  Wildcards * and ? are
permitted and when used, all matching files will be extracted.


Possible problems
-----------------

I am not sure completely how to dinguish a MyDos disk from an Atari Disk.
Currently if there are more than 721 sectors, It assumes MyDos.  The main
difference is that MyDos disks greater than a certain size use the bits
used on an Atari Disk to hold the file No, to allow larger sector links.
It should work properly for most mega size images and standard single and
double density disks.


Misc
----

Anyone with information on Sparta Dos or other disk formats drop me a line.
I am also interested in algorithms for determining the DOS format of a disk.
Specifically MyDos 1050 Density vs Atari 1050 Density,  How to tell if a
disk is in Atari or MyDos format.  I think Mydos doesn't store File Number
within each sector along with the sector link information when there is above
a certain number of sectors.  Also complete Docs on DCM format would be
appreciated.
