py2exe越来越爽了

新版本已经可以打包为一个文件了，以前都是一堆dll, pyd的。具体的变化其实只有一个地方。就是options里增加bundle_files项，值为1表示pyd和dll文件会被打包到exe文件中，且不能从文件系统中加载python模块；值为2表示pyd和dll文件会被打包到exe文件中，但是可以从文件系统中加载python模块。另外setup中使用zipfile=None可以不生成library.zip。

例如原来的：

from distutils.core import setup
import py2exe
includes = ["encodings", "encodings.*"]
options = {"py2exe":
            {   "compressed": 1,
                "optimize": 2,
                "includes": includes,                
            }
          }
setup(   
    version = "0.1.0",
    description = "search panda",
    name = "search panda",    
    options = options,    
    windows=[{"script": "search.py", "icon_resources": [(1, "search.ico")] }],      
    )
只需要改为：
from distutils.core import setup
import py2exe
includes = ["encodings", "encodings.*"]
options = {"py2exe":
            {   "compressed": 1,
                "optimize": 2,
                "includes": includes,
                "bundle_files": 1
            }
          }
setup(   
    version = "0.1.0",
    description = "search panda",
    name = "search panda",
    options = options,
    zipfile=None,
    windows=[{"script": "search.py", "icon_resources": [(1, "search.ico")] }],  

    )
