Lib path declaration

[santhosh_89]

Hi Monks

I have downloaded a cpan module called Config::Abstract::Ini,It is available in my home directory and /usr/lib also.Default the @INC will have the /usr/lib path.But I want to take and use my home directory module.The path will be given from global values.If the values is empty,it should take default path(/usr/lib).If the home directory path is error,it should say an error.

    if($path ne ''){
        unshift(@INC,"$path");
    }
    use Config::Abstract::Ini;

NOTE: I used above code it is searching from default directory.even I would give wrong path in global value.
