Howto apply patch

====generate a patch file======

diff -Naurp old_file new_file > production.patch
產生patch file是用diff指令，至於要下哪些參數可以
參考diff --help來使用


====apply patch file======
patch
-p之後接數字代表要patch(更新)的file目
錄檔案從哪邊開始可以參考patch file的
第一行所寫的路經

patch -p數字 < patch_file_path

還原:
 patch -R <  patch_file_path
