Python提取Linux内核源代码的目录结构实现方法

# @This script can be used to iterate the given directory,and create the 

# empty directory structure without file in it,e.g,I want to have you directory

# as the linux kernel source, but i don't want the files, then this script comes.

# @This script is running under python 3.1

#level:目录的层数，不要也可以，主要是为了显示目录在那一层

#srcpath:内核源代码所在的路路径

#destpath:将要生成的内核源代码的目录结构所在路径
