# For the validation itself, the plugin calls this script without

# format:

# domain keyauth
#
# where `domain` is the domain to validate, and `keyauth` is a
# key authorization string (draft-ietf-acme-acme-01, §7.1) of
# the form `token.account_key`.
#
# To complete the challenge, write the key authorization string
# into a file `.well-known/acme-challenge/token`, available
# through HTTP on the requested domain.
