###ACME_DEPLOY_SSH_CMD
You can customize the ssh command used to connect to the remote host. For example
if you need to connect to a specific port at the remote server you can set this
to, for example, "ssh -p 22"
###ACME_DEPLOY_SSH_SERVER
URL or IP Address of the remote server. If not provided then the domain
name provided on the acme.sh --deploy command line is used.
###ACME_DEPLOY_SSH_PORT
Port number that SSH will attempt to connect to at the remote server. If
not provided then defaults to 22.
###ACME_DEPLOY_SSH_SERVICE_STOP
Command to execute on the remote server prior to copying any certificates. This
would typically be used to stop the service for which the certificates are
being deployed.

###ACME_DEPLOY_SSH_CAFILE

###ACME_DEPLOY_SSH_FULLCHAIN
Target filename for the fullchain certificate issued by LetsEncrypt.
If this is the same as a previous filename then it is appended to the same

###ACME_DEPLOY_SSH_REMOTE_CMD
Command to execute on the remote server after copying any certificates. This
could be any additional command required prior to starting the service again,
or could be a all-inclusive restart (stop and start of service). If
ACME_DEPLOY_SSH_SERVICE_STOP value was provided then a 2 second sleep is
inserted prior to calling this command to allow the system to stabalize.
###ACME_DEPLOY_SSH_SERVICE_START
Command to execute on the remote server after copying any certificates. This
would typically be used to stop the service for which the certificates are
being deployed. If ACME_DEPLOY_SSH_SERVICE_STOP or ACME_DEPLOY_SSH_REMOTE_CMD

##Backups
###Backups
Before writing a certificate file to the remote server the existing
certificate will be copied to a backup directory on the remote server.
These are placed in a hidden directory in the home directory of the SSH
