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 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 persistent 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 workaround was to force
       the "BEGIN" block to be executed again:

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