# 原作者为：bones7456, http://li2z.cn/
# 修改者为：decli@qq.com
# v1.2，changeLog：
# +: 文件日期/时间/颜色显示、多线程支持、主页跳转
# -: 解决不同浏览器下上传文件名乱码问题：仅IE，其它浏览器暂时没处理。
# -: 一些路径显示的bug，主要是 cgi.escape() 转义问题
# ?: notepad++ 下直接编译的server路径问题
"""
简介：这是一个 python 写的轻量级的文件共享服务器（基于内置的SimpleHTTPServer模块），
支持文件上传下载，只要你安装了python（建议版本2.6~2.7，不支持3.x），
然后去到想要共享的目录下，执行：
python SimpleHTTPServerWithUpload.py 1234
其中1234为你指定的端口号，如不写，默认为 8080
然后访问 http://localhost:1234 即可，localhost 或者 1234 请酌情替换。

"""Simple HTTP Server With Upload.
This module builds on BaseHTTPServer by implementing the standard GET
and HEAD requests in a fairly straightforward manner.
