=head1 NAME

updatenow - updates /usr/local/cpanel from update servers

=head1 USAGE

    # Called from upcp like this:
    # --force tells updatenow to sync even if the version has not changed (similar to --sync). This setting will also bypass cron detection.
    updatenow --upcp

    # upcp will call this script like this if upcp is called with --force
    updatenow --upcp --force

    # If files which this script manages somehow get deleted, this will re-sync them but not upgrade.
    # This is used by other cpanel scripts as a safety measure.
    updatenow.static --sync

    # Used by cpanel installer prior to vps optimization
    updatenow --no-check-perl

=head1 DESCRIPTION

NOTE: Under most circumstances, you should never call this script directly. B</usr/local/cpanel/scripts/upcp>, called with an optional [--force]
should be all you need. --sync is only intended to be called by other cpanel scripts when it appears that cpanel managed files
have been deleted.

The normal usage of this script is to update cpanel to the latest version of your TIER I<(see /etc/cpupdate.conf)>.
By default, no update is done by default if you are already on that version. The UPDATES setting in cpupdate.conf
is also honored when the environment variable CPANEL_IS_CRON is set (usually from upcp).

If an HTTPUPDATE= setting is present in /etc/cpsources.conf with a hostname, this will be the preferred source to sync from.
