+Udis86
+======
+
+Udis86 is a disassembler for the x86 and x86-64 class of instruction set
+architectures. It consists of a C library called libudis86 which
+provides a clean and simple interface to decode a stream of raw binary
+data, and to inspect the disassembled instructions in a structured
+manner.
+
+
+LICENSE
+-------
+
+Udis86 is distributed under the terms of the 2-clause "Simplified BSD
+License".  A copy of the license is included with the source in LICENSE.
+
+
+libudis86
+---------
+
+  o Supports all x86 and x86-64 (AMD64) General purpose and
+    System instructions.
+  o Supported ISA extensions:
+    - MMX, FPU (x87), AMD 3DNow
+    - SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES,
+    - AMD-V, INTEL-VMX, SMX
+  o Instructions are defined in an XML document, with opcode
+    tables generated for performance.
+  o Supports output in both INTEL (NASM) as well as AT&T (GNU as) style
+    assembly language syntax.
+  o Supports a variety of input methods: Files, Memory Buffers, and
+    Function Callback hooks.
+  o Re-entrant, no dynamic memory allocation.
+  o Fully documented API
+
+
+  -- EXAMPLE -----------------------------------------------------------
+
+    ud_t u;
+
+    ud_init(&u);
+    ud_set_input_file(&u, stdin);
+    ud_set_mode(&u, 64);
+    ud_set_syntax(&u, UD_SYN_INTEL);
+
+    while (ud_disassemble(&u)) {
+      printf("\t%s\n", ud_insn_asm(&ud_obj));
+    }
+
+  ----------------------------------------------------------------------
+
+
+udcli
+-----
+
+udcli is a small command-line tool for your quick disassembly needs.
+
+  -- EXAMPLE -----------------------------------------------------------
+
+    $ echo "65 67 89 87 76 65 54 56 78 89 09 00 90" | udcli -32 -x 
+    0000000080000800 656789877665     mov [gs:bx+0x6576], eax
+    0000000080000806 54               push esp
+    0000000080000807 56               push esi
+    0000000080000808 7889             js 0x80000793
+    000000008000080a 0900             or [eax], eax
+    000000008000080c 90               nop

+
+
+Documentation
+-------------
+
+The libudis86 api is fully documented. The package distribution contains
+a Texinfo file which can be installed by invoking "make install-info".
+You can also find an online html version of the documentation available
+at http://udis86.sourceforge.net/.
+
+
+Autotools Build
+---------------
+
+You need autotools if building from sources cloned form version control
+system, or if you need to regenerate the build system. The wrapper
+script 'autogen.sh' is provided that'll generate the build system.
