Poke is an interactive, extensible editor for editing structured binary data. It's goal is to serve as a tool to aid in the development of programs that operate on binary files, such as assembler as linkers, as well as for reverse engineering of protocols and formats, prototyping of other programs like linkers, compressors or filters. It is also intended to serve as a convenient foundation to write other utilities such as diff and patch tools for binary files. It is also superfun to hack!
