8.48: How do I add the directory my program lives in to the module/library
search path?

    (contributed by brian d foy)

    If you know the directory already, you can add it to @INC as you would
    for any other directory. You might <use lib> if you know the directory
    at compile time:

            use lib $directory;
    The trick in this task is to find the directory. Before your script does
    anything else (such as a "chdir"), you can get the current working
    directory with the "Cwd" module, which comes with Perl:

            BEGIN {
                    use Cwd;
                    our $directory = cwd;
            use lib $directory;
    You can do a similar thing with the value of $0, which holds the script
    name. That might hold a relative path, but "rel2abs" can turn it into an
    absolute path. Once you have the

            BEGIN {
                    use File::Spec::Functions qw(rel2abs);
                    use File::Basename qw(dirname);
                    my $path   = rel2abs( $0 );
                    our $directory = dirname( $path );
            use lib $directory;

    The "FindBin" module, which comes with Perl, might work. It searches
    through $ENV (so your script has to be in one of those
    directories). You can then use that directory (in $FindBin::Bin) to
    locate nearby directories you want to add:

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