# NAME

FindBin - Locate directory of original perl script

# SYNOPSIS

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

     or

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

# DESCRIPTION

Locates the full path to the script bin directory to allow the use of paths relative to the bin directory.

This allows a user to setup a directory tree for some software with directories <root>/bin and <root>/lib and then the above example will allow the use of modules in the lib directory without knowing where the software tree is installed.

If perl is invoked using the -e option or the perl script is read from STDIN then FindBin sets both `$Bin` and `$RealBin` to the current directory.

# EXPORTABLE VARIABLES

     $Bin         - path to bin directory from where script was invoked
     $Script      - basename of script from which perl was invoked
     $RealBin     - $Bin with all links resolved
     $RealScript  - $Script with all links resolved

# KNOWN BUGS

if perl is invoked as

       perl filename

and filename does not have executable rights and a program called filename exists in the users `$ENV{PATH}` which satisfies both -x and -T then FindBin assumes that it was invoked via the `$ENV{PATH}`.

Workaround is to invoke perl as

     perl ./filename
