hachoir-urwid is a binary file explorer that uses
the Hachoir library to parse files. Using this
tool, you can know the exact meaning of each
bit/byte of your files. With direction keys, you
can navigate in the field tree. The key 'h' will
disable 'human display' and switch to 'raw
display'. It's sometimes useful when you would
like to compare hexadecimal data and Hachoir
representation.
