application: guestbookapplication放的就是Project檔的名稱(上傳至GAE時，就依此名稱存放，因此必須是有註冊成功的名稱才行)，version就是目前的開發版本，允許的版本號的範圍為^(?!-)[a-z\d\-]{1,100}$，有興趣的可以試試不一樣的版本號:)
version: 1
runtime: python
api_version: 1
handlers:
- url: .*
script: guestbook.py
handlers:根據上面這個app.yaml的設定，當url為/images/.*時，會直接從images這個資料夾找到相同名稱的檔案上傳。同樣的，/js/.*也是一樣的做法。而其他所有的url，全會交由myapp.py處理。
- url: /images
static_dir: images
- url: /js
static_dir: js
- url: /.*
script: myapp.py
dev_appserver.py myapp/
dev_appserver.py demos/guestbook
appcfg.py [options] update <app-directory>輸入的<app-directory>必須要包含app.yaml，上傳的檔案會根據app.yaml的設定去搜尋需要上傳的檔案。且會根據app.yaml中設定的application名稱，上傳至你註冊的GAE application。上傳時，會詢問你的email和密碼，也可以在[options]裡面，指定--email=...，就不用每次上傳時都手動輸入了。相關的參數請參考。

#include <unistd.h>這是一個簡單的設定Timer介面。當呼叫了alarm( n )後，等待n秒後，就會觸發一次的SIGALRM的signal，所以必須要在呼叫alarm前，先設好SIGALRM的handler function才行。而當乎呼alarm(0)時，則表示停止當前的timer處理，不要發出SIGALRM的signal。
