 * **debug output:** for script debugging please set the config option 'adb\_debug' to '1' and check the runtime output with _logread -e "adblock"_
 * **storage expansion:** to process and store all block list sources at once it might helpful to enlarge your temp directory with a swap partition => see [openwrt wiki](https://wiki.openwrt.org/doc/uci/fstab) for further details
 * **add white-/blacklist entries:** add domain white- or blacklist entries to always-allow or -deny certain (sub) domains, by default both lists are empty and located in _/etc/adblock_. Please add one domain per line - ip addresses, wildcards & regex are _not_ allowed (see example below)

 The query function checks against the submitted (sub-)domain and recurses automatically to the upper top level domain(s).
 For every domain it returns the overall count plus a distinct list of active block lists with the first relevant result.
