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 direc-
       tory.

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 ISSUES

       If there are two modules using "FindBin" from different directories
       under the same interpreter, this won't work. Since "FindBin" uses a
       "BEGIN" block, it'll be executed only once, and only the first caller
       will get it right. This is a problem under mod_perl and other persis-
       tent Perl environments, where you shouldn't use this module. Which also
       means that you should avoid using "FindBin" in modules that you plan to
       put on CPAN. To make sure that "FindBin" will work is to call the
       "again" function:

         use FindBin;
         FindBin::again(); # or FindBin->again;

       In former versions of FindBin there was no "again" function. The work-
       around was to force the "BEGIN" block to be executed again:

         delete $INC{'FindBin.pm'};
         require FindBin;

KNOWN BUGS

       If perl is invoked as

          perl filename
