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


AUTHORS
       FindBin is supported as part of the core perl distribu-
       tion. Please send bug reports to <perlbug@perl.org> using
