optionally the `api-ssl` service.

+#
+# mikrotik.sh
+# ===========
+#
+# Deploy certificate to a Mikrotik RouterOS system using the SSH protocol.
+#
+# The script must be able to connect to the remote host without a password.
+# Therefore only public key authentication method is available and SSH keys must
+# have been exchanged prior to running this script.
+#
+#
+# Variables
+# ---------
+#
+# The following variables can be exported in order to configure the script's
+# behavior. When not set, values previously saved in _domain.conf_ are taken.
+#
+#
+# DEPLOY_MIKROTIK_SET_API
+# :    Deploy certificate also to the API-SSL service.
+#
+# DEPLOY_MIKROTIK_SSH_HOST
+# :    Hostname or IP address to connect to the remote host. When not provided
+#      use the domain name from the `acme.sh` command.
+#
+# DEPLOY_MIKROTIK_SSH_IDFILE
+# :    Selects a file from which the identity (private key) for public key
+#      authentication is read. When not provided, `ssh` default is used.
+#
+# DEPLOY_MIKROTIK_SSH_OPTIONS
+# :    Additional options to pass to the `ssh` process.
+#
+# DEPLOY_MIKROTIK_SSH_PORT
+# :    Port to connect to on the remote host.
+#
+# DEPLOY_MIKROTIK_SSH_USER
+# :    Specifies the user to log in as on the remote machine. When not provide
+#      use the current user name.
