--repo=<name> Treats the sync source as a named repo that supports versioning.
--signed=[1|0] Enforce GPG signature verificaiton for the .cpanelsync files.
--vendor=<name> Specifies the vendor to use with GPG signature verification.
Defaults to 'cpanel'
--categories=<name> Specifies the vendor keyring to use with GPG signature verification.
Defaults based on the globally configured TweakSetting.
--quiet=1 Suppress HttpRequest output.
Arguments:
host The mirror to download from. Normally httpupdate.cpanel.net
url The mirror URL that represents the base of the cpanelsync repo.
Defaults to '/'
root The local directory that is being synced. Defaults to '/'.
Notes:
This script no longer supports syncing directly against named cPanel tier targets
such as RELEASE or STABLE. The cPanel update system in all releases after 11.30
uses a separate cpanelsync v2 system and should be updated using upcp or updatenow.
