a2tools for ProDOS (?)

[Chris Morse <chris@cosmicwolf.com>]

I'm doing some Apple II development using the CC65 6502 C compiler and
their CA65 assembler.  I found a nice tool called "a2tools" that lets
me easily inject/copy my final binary program into an Apple II .DSK
image for use with an emulator.  A2TOOLS works with DOS 3.3 disks.
You can find it here:

I'm wondering if there is a command-line utility like this that will
work with ProDOS-8 disk images.  Anyone know of one?  I have a
registered copy of Apple ][ Oasis, and their file manager can do the
job, but it's not quite and must be done manually ; it would be much
nicer if my 'compile.bat' file could do the job for me using a
command-line tool.

Thanks,
