Usage: is_update_available [--verbose|-v]

Determines whether the installed cPanel & WHM version matches the
version currently advertised by the httpupdate mirrors. If the
CPANEL setting in /etc/cpupdate.conf is pinned to an explicit
11.X.X.X build, that build is compared directly without contacting
the mirrors.

Exit status:
    0   An update is available (installed version does not match).
    1   No update is available (installed version matches, or the
        target could not be determined).
    2   Invalid command-line arguments.

Options:
    -v, --verbose   Print "Up to date" or "New Version X.X.X.X available"
                    before exiting.
    -h, --help      Show this help and exit 0.
EOM
