+.Description
+
+這是一個簡單的 *GNU makefile for 'C++' project*
+類似AutoTool等工具, 不過又更簡化了, 操作方法是利用GNUMakefile裡的targets
+當作指令, 生出一個targets檔, 以後鍵入 `make all` 就會自動把所有targets都
+編譯出來.
+
+.Commands
+
+* `make init` +
+初始化, 設定完之後所在位置會多幾個資料夾如下
+
+** 'bin/' 放編譯出來的執行檔
+** 'dep/' dependency相關資料, 內容會自動生成, 不用理它
+** 'inc/' 自定義的include file放置位置
+** 'src/' source code放置位置
+** 'obj/' obj file放置位置, 會自動生成, 不用理它
+
+* `make new NAME=<name> [OBJS=<OBJ_FILES> LIBS=<LIBRARIES>]` +
+新增一個target, 須給定目標名 , 並且此Makefile會假定 `main() { ... }` 放在
+'src/<name>.cpp' 而最終輸出會是 'bin/<name>' . +
+關於 'OBJS=' 與 'LIBS=' 參考下面說明
+
+* `make add NAME=<name> [OBJS=<OBJ_FILES> LIBS=<LIBRARIES>]` +
+針對target為 '<name>' 的目標新增需要的 '<OBJ_FILES>' , 與 '<LIBRARIES>'. 
+'<LIBRARIES>' 的部份會用 `pkg-config` 去解讀, 例如 '<LIBRARIES>' 為
+'opencv lapackpp' 則link時會被以下指令展開 +
+`pkg-config --libs opencv lapackpp` +
+而 '<OBJ_FILES>' 的部份則只需要給 *name* 就好, 不需要有完整個 pathname, 例如
+例如 '<OBJ_FILES>' 是 'a b c' 則此makefile會視為
+
+** source code: 'src/a.cpp src/b.cpp src/c.cpp'
+** obj file: 'obj/a.o obj/b.o obj/c.o'
+
+* `make del NAME=<name> [OBJS=<OBJ_FILES> LIBS=<LIBRARIES>]` +
+與 add相反, 嘗試將指定target所需的'<OBJ_FILES>'和'<LIBRARIES>'移除
+
+* `make clean` +
+將 'bin/*' 'dep/*' 'obj/*' 清除, 有時候覺得dependency怪怪的
+時可以嘗試執行此指令
+
+[NOTE]
+其中整個project到底有哪些obj file會完全依照 *src/* 裡面有哪些 `.cpp` 檔決定
+
+===== GNUMakefile
+
+就是一個 Makefile, 不過裡面有些東西是 `GNU-make` only的
+
+===== GNUMakefile.dependency.bash
+
+產生 dependency檔用的
