+## Parsing
+
+Here a script (dash and ash complaint) to generate a list of all infos:
+```sh
+#!/bin/ash
+for f in ./dnsapi/dns_*.sh
+do
+  filename=$(basename -- "$f")
+  dns_api="${filename%.*}"
+  echo "$dns_api"
+  dns_api_info_var="${dns_api}_info"
+  # shellcheck source=./dnsapi/dns_*.sh
+  . "$f"
+  info=""
+  eval info=\$$dns_api_info_var
+  echo "$info"
+done
+```
+
+Now execute it and stored result to info.txt file:
+
+   sh ./dns_info.sh > info.txt
+
+The resulted file has size of 39Kb bytes and gzipped it's about 10Kb.
