Some users have issues in java environment configuration witch leads to an extra line when executing java scripts like baksmali , dx , etc ...
Instead solving their java error witch is out of my scope , it was better to change the script to catch the line we need to identify what setup and chk tools scripts need to get thru .
chk_tools was created to verify if all tools required for fatrat exists in user OS and will also check their versions (in case necessary) .
Chk_tools will provide user a solution for the problem in case it detects any missing package or incorrect version
