A bash script that wraps dwarfdump to help linking binary to source code and
debuging binary code with out rebuilding with source code.
思路源自美团的美团 iOS 工程 zsource 命令背后的那些事儿，制作的简易Bash版。
简单来讲就是解析指定的二进制文件(第一个路径参数)，获取到编译该二进制时的文件路径，然后在本地建立一个相同路径的文件夹，然后把源码复制或者链接过去(第二个路径为对应的源码文件夹)。
# for binary in framework
./dsource.sh -l /path/to/xxx.framework/xxx /path/to/releated/xxx/source/
# or for .a file
./dsource.sh -l /path/to/xxx.a /path/to/releated/xxx/source/
copy this script to /usr/local/bin/ to use globally.
Incase some mismatch, you can use dsource.sh -f to find the compile directory and create it manually by mkdir -p,
copy source code to that path, and run dsource.sh -c to check if it matches,
modify the path name or hierarchical structure if neeeded.
