## update.sh - manage a OpenWRT LetsEncrypt https instalation
# HOWTO: 
# - put update.sh in its own directory (like /root/.https)
# - run ./update.sh your.domain.com (that domain needs to point to your router)
#  * this get an issued cert from letsencrypt.org using the webroot verification method
#  * also installs curl and ca-certificates packages
# - use crontab -e; add the line `0 0 * * * "/root/.https/update.sh" >>/root/.https/log.txt 2>&`
#  * this runs the update every day, logging everything to log.txt
