# - cap-2 produces '@', and not '"', without that, typing
# email addresses becomes a major pain with a qwerty
# keyboard. note that you can type '"' with fn-E anyway.

* - The disassembly function returns a string instead of writing it to a

*
* - All the references to the struct "disassemble_info" have been removed.
*
* - A set of enums for the thumb opcodes have been defined, along with a
* "decode()" function that maps a thumb instruction to an opcode enum.
*
* - Eliminated uses of the special characters ', `, and ? from the
