====== NDK Shell for Linux/Cygwin(Windows) ======
自己简单封装了一下ndk-build

支持：
  - 通过修改build-static-library.mk,可以生成静态库
  - 直接解析Android.mk，支持设置安装目录，支持自动拷贝依赖的静态库
  - 添加了系统检测，同时支持Linux和Cygwin(Windows)环境。

使用方法
  - 和以前一样,只是直接调用脚本名字ndk。
  - 支持原来ndk-build参数，如：ndk clean,ndk -h等。

update note:
  - 解决了Windows下make.exe和Symbian编译环境的冲突
  - 同时支持了Linux和Cygwin(Windows)环境下编译

<file lang=shell ndk.sh>
#!/bin/sh

#Your Android.mk Maybe need to add INSTALL_DIR and MY_STATIC_LIBRARIES.
#Now it just support parse these variables:
#   INSTALL_DIR =>Where you want to install the static library.
#   MY_STATIC_LIBRARIES =>Some dependent static libraries,with the full path or relative path.
#NOTICE:
#1.This shell just support parse MY_STATIC_LIBRARIES like this:
#	MY_STATIC_LIBRARIES = ../libafc.a
#	MY_STATIC_LIBRARIES = ../libutf8.a
#2.If you need to run this shell,you must cd to the RIGHT directory
#You MUST see ./${ANDROID_MK},then this shell will run,otherwise it will exit.
