Most of this is a matter of I need command-line tools for my various 
projects and it simplified stuff.  I still have to figure out how to 
reliably write to DOS 3.3 disk images.

http://usotsuki.info/dos3.3/dir33.c <-- Lists all files in a disk image.
http://usotsuki.info/dos3.3/get33.c <-- Extracts a file from a disk image.
http://usotsuki.info/dos3.3/trimpg2.c <-- Trims junk off a binary file.

trimpg2 is needed because some of my other stuff assumes that a binary 
file's length is the length of the program contained within plus 4.  It 
reads from the file, then overwrites it with the fixed number of bytes.

dir33's output should be identical to CATALOG.

This now simplifies some of the stuff for Apple Crunch as I no longer have 
to put the files on a ProDOS disk, translate to some wacky interleaved 
disk format, extract and reapply the header as before.  I still have to 
use ApplePC and the text-file trick to put files back.

-- Keep in mind I'm not a Windows user anymore and prefer tools that run 
directly from the command line as I can use the power of Bash to improve 
them.  These tools are designed for a specific task, and work well at it.
