      HOON, an AT&T to Shellcode
    ------------------------------------------------------------------------

    DETAILS

    HOON is a python shellcode creator. It does not just create shellcode, it
    can parse AT&T's syntax assembler and create the shellcode from that.

    HOON is a product of not having a decent PUBLIC shellcode creator and it
    works pretty well too. Some things to note though, it does not have a huge
    instruction/opcode database and this will be fixed in future releases. It
    also does not handle jump/call's very well or addressing (movl (%eax),%esi
    for example) these are minor issues. Most definitely have a look at the
    tokening system - if someone can port this to Intel syntax, it would be
    great.

    To add more entries, go to the init (not __init__) method and use
    self.addreg (ignore the name ;)) with the instruction/format of
    instruction/opcode. Opcode will need a base (commonly \xc0) if it's all
    register instruction.

    single instruction:
    self.addreg("int3",self.format["single"],"\xcc")
    instruction with format instruction reg,reg
    self.addreg("movl",self.format["insregreg"],"\xc7\xc0")

     * note, Python (not ActivePython) doesn't like values with it's strips()
    so change that will a replace(self.null,"")
