簡介
-----
Pyssy 是一系列用於 `上海交通大學 飲水思源站 <http://bbs.sjtu.edu.cn>`_ 的Python腳本。
Pyssy 既可以寄宿在Sina App Engine上，也可以單獨使用。
----------
依賴項
----------
========== ======================================================
Flask Pyssy使用Flask作爲網頁服務框架。
pylibmc 託管在SAE上的Pyssy使用pylibmc訪問SAE的memcached服務。
Redis-py 獨立運行的Pyssy使用Redis作爲memcached服務的替代。
