+# GeoIP checking
+#
+# This can be used to pre-select a language based on the country
+# the user is currently in. It *assumes* that there's internet
+# connectivity, though. Configuration is like in the locale module,
+# but remember to use a URL that returns full data **and** to
+# use a selector that will pick the country, not the timezone.
+#
+# To disable GeoIP checking, either comment-out the entire geoip section,
+# or set the *style* key to an unsupported format (e.g. `none`).
+# Also, note the analogous feature in `src/modules/locale/locale.conf`,
+# which is where you will find complete documentation.
