該例項主要實現讀取乙個任務檔案, 根據指定的任務引數自動備份.
任務檔案的格式: (注意,分號後面注釋是不支援的)
[task] ; 一項任務開始
dir=h:/project ; 指定備份的目錄
recusive=1 ; 是否遞迴子目錄
suffix=h|cpp|hpp|c|user|filters|vcxproj|sln|css|gif|html|bmp|png|lib|dsw|dsp|htm|html|ico|ini|jpg|rc|vssscc ; 指定備份的副檔名
exclude=0 ; 指定是備份上面的引數指定的副檔名還是排除指定的副檔名
; 備份後的檔案路徑名
python**如下:
# -*- coding: utf-8 -*-
