## 8.84 FindBin

Finds the full path to a script's bin directory, letting you use relative paths to that directory without needing to know the actual location:

>     use FindBin;
>     use lib "$FindBin::Bin/../lib";

or:

>     use FindBin qw($Bin);
>     use lib "$Bin/../lib";

FindBin exports the following variables:

`$Bin`

  Path to bin directory from which script was invoked.

`$Script`

  Basename of script from which Perl was invoked.

`$RealBin`

  `$Bin` with all links resolved.

`$RealScript`

  `$Script` with all links resolved.

If you invoke Perl with the -e option or read the Perl script from STDIN, then FindBin sets both `$Bin` and `$RealBin` to the current directory.
