-bin causes CASM to generate single or multi record files depending on
the size of the output file. Each record can be up to 32k before it
starts a new record. I'm in the process of updating it to allow for a
full 64k record. I know that some of the CoCo assemblers like Macro-80c
and Edt/Asm 64, and Edt/Asm III used to generate multiple record with
128 to 256 bytes per record depending on the assembler.

The formats that are implemented or are planned are as follows:

-bin    - RS-DOS binary
-rom    - Padded ROM file
-os9    - OS-9 module (via mod directive)
-raw    - raw binary output (same as -rom but with no padding)
-s19    - Motorola S Record format (historical legacy)
-mod    - Shared library module
-noout  - Disables the creation of the output file (used for debugging)


Currently the -rom option relies on -romsize in order to specify a size
other than 8k. The next release will change this and use the CCASM
syntax of -rom[=size]


The following formats are planned but not completed:

-rof    - RMA relocatable object file (ROF)
-erof   - Extended ROF (dependant on ROF support)



Some other options are:

-6309         - Enable 6309 opcodes
-I=directory  - Add directory for includes/lib/use
-O=directory  - Set the output directory
-D=label      - Define label
-C            - Use case sensative labels (dunno if this still works)
-N            - Sets the output name


Some of the options are legacy and may or may not work. I'm revamping
all of the options for the next release and quite a few have been added
including fixes for several of the listing output options for using CASM
as a preprocessor to output source with expanded macros.
