Today I was a little bored, so I created simple ADB & Fastboot command line procesor.
I'm not really sure that this application is practical.
You don't need to type "adb" or "fastboot" everytime. If CLP shows "ADB >> ", then type command you want to run, for example "shell ls /data/app".
I have no time for descripting this app, just use it and check out.
Works only with Windows.
