= 參考一 ： Debian 無痛起步法- 自己動手製作.deb 檔 =
 * [http://people.debian.org.tw/~moto/debian/DebianLessPain/Debian-Install-Guide-12.html Debian 無痛起步法( 線上最新版): 自己動手製作.deb 檔]
 * 用google 搜尋 "deb 製作" 最直接的連結為上面的內容，然而無痛的結果應該是"看完還是不會做"吧!(個人感覺)

= 參考二： 用Open Source工具開發軟體- 套件包裝製作 =
 * [http://www.study-area.org/tips/opentools/opentools/x1425.html 用Open Source工具開發軟體:套件包裝製作]
 * 這篇寫的比較詳細，可以參考

= 參考三： 用Jazz的Hadoop打包方式 =
 * [http://trac.nchc.org.tw/cloud/wiki/jazz/Hadoop_deb Hadoop_deb製作]
 * 這篇是hadoop的deb打包過程，不過有些細節沒有寫到，因此來補完。

= 前言 =
 * 要學習如何包裝nutch 的 deb檔
 * 然而目前大部分找到的說明是適用於 c code等要configure , make , make install 的專案，才會很簡單的用以下方法來完成製作deb
   * 目錄名稱如 '''pkgname-version''' ，例： hadoop-0.19
   * 在source code內執行'''dh_make'''
   * 修改 新產生debian資料夾內的設定檔
   * 執行'''dpkg-buildpackage -rfakeroot'''
 * 不過hadoop 與 nutch都是java code，沒有make or configure檔，因此試過上面的方法會遇到錯誤
 * 因此此篇適合用在：打包已經compiler好的可執行檔，並搭配設定好的配置檔來做簡便安裝用途者
= 步驟 =
== 製作deb打包設定檔 ==

{{{
$ mkdir -p ~/test/hadoop-0.19.1/debian
$ cd ~/test/hadoop-0.19.1/debian
}}}

== 編輯檔案 ==
   * 這些與dh_make產生出來的檔案差不多，就不討論了
