 +# Here is a script to deploy cert to routeros router.
 +# Deploy the cert to remote routeros
 +#
 +# ```sh
 +# acme.sh --deploy -d ftp.example.com --deploy-hook routeros
 +# ```
 +#
 +# Before you can deploy the certificate to router os, you need
 +# to add the id_rsa.pub key to the routeros and assign a user
 +# to that key.
 +#
 +# The user need to have access to ssh, ftp, read and write.
 +#
 +# There are no need to enable ftp service for the script to work,
 +# as they are transmitted over SCP, however ftp is needed to store
 +# the files on the router.
 +#
 +# Then you need to set the environment variables for the
 +# deploy script to work.
 +#
 +# ```sh
 +# export ROUTER_OS_USERNAME=certuser
 +# export ROUTER_OS_HOST=router.example.com
 +#
 +# acme.sh --deploy -d ftp.example.com --deploy-hook routeros
 +# ```
 +#
 +# The deploy script will remove previously deployed certificates,
 +# and it does this with an assumption on how RouterOS names imported
 +# certificates, adding a "cer_0" suffix at the end. This is true for
 +# versions 6.32 -> 6.41.3, but it is not guaranteed that it will be
 +# true for future versions when upgrading.
 +#
 +# If the router have other certificates with the same name as the one
 +# beeing deployed, then this script will remove those certificates.
 +#
 +# At the end of the script, the services that use those certificates
 +# could be updated. Currently only the www-ssl service is beeing
 +# updated, but more services could be added.
 +#
 +# For instance:
 +# ```sh
 +# export ROUTER_OS_ADDITIONAL_SERVICES="/ip service set api-ssl certificate=$_cdomain.cer_0"
 +# ```
 +#
 +# One optional thing to do as well is to create a script that updates
 +# all the required services and run that script in a single command.
 +#
 +# returns 0 means success, otherwise error.
