Hexify is a hex dump utility handy for viewing binary files at the command-prompt.
Hexify can be seen as an alternative or improvement to Tony Dycks' readbin.py. It is more compact, more Pythonic, and slightly more feature-rich (command-line parameters, exit codes, jump-to location, etc). I have kept his output format and platform-dependent display clearing.
By implementing the bulk of the functionality as a class, the code can be more-readily adapted to other display environment. I would like an HTML-friendly version, for example. Other possible enhancements include adding a parameter to specify a display range.
This code demonstrates argument processing, data type conversion, exception handling, raw input, and some rudimentary file handling.
