#         ==================================================            #
#         $ Mikrotik RouterOS update script for CloudFlare $            #
#         ==================================================            #
#                                                                       #
# - You need a CloudFlare account & api key (look under settings),      #
#   a zone and A record in it                                           #
# - All variables in first section are obvious, except CFid,            #
#   To obtain CFzoneid use following command in any unix shell:         #
#    curl -X GET "https://api.cloudflare.com/client/v4/zones" -H "X-Auth-Email: YOUR_EMAIL" -H "X-Auth-Key: YOUR_API_KEY" -H "Content-Type: application/json" | python -mjson.tool 
#   To obtain CFid use following command in any unix shell:             #
#    curl -X GET "https://api.cloudflare.com/client/v4/zones/YOUR_ZONE_ID/dns_records" -H "X-Auth-Email: YOUR_EMAIL" -H "X-Auth-Key: YOUR_API_KEY" -H "Content-Type: application/json" | python -mjson.tool
# - Enable CFDebug if needed - it'll print some info to logs            #
# - Put script under /system scripts giving "read,write,ftp" policy access.       #
#   For 6.29 and older "test" policy is also needed.                    #
# - Add script to /system scheduler using it's name in "on-event"       #
# - Requires at least RouterOS 6.44beta75 for multiple header support   #
#                                                                       #
