      r2 is a complete rewrite of radare. It provides a set of libraries, tools
      and plugins to ease reverse engineering tasks. Distributed mostly under
      LGPLv3, each plugin can have different licenses.

      The radare project started as a simple command-line hexadecimal editor
      focused on forensics. Today, r2 is a featureful low-level command-line
      tool with support for scripting with the embedded JavaScript interpreter
      or via r2pipe.

      r2 can edit files on local hard drives, view kernel memory, and debug
      programs locally or via a remote gdb/windbg servers. r2's wide
      architecture support allows you to analyze, emulate, debug, modify, and
      disassemble any binary.
