+#  Example utility for accessing the Taginfo API

+#  The tool will send the request to the server, get the JSON result and
+#  print it out in an easier to read form.

+#  You can set the following environment variables (default in brackets):
+#    TAGINFO_API_SERVER   [taginfo.openstreetmap.de]
+#    TAGINFO_API_PORT     [80]
+#    TAGINFO_API_VERSION  [2]
