FindBin - phpMan

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;
