-### TCP listener ##########
96 
-# Listen <socketname> <porttype> tcp <address to bind> <port> <options...>
97 
-#       socketname: any name you wish to show up in logs and statistics
98 
-#       porttype: one of:
99 
-#               fullfeed - everything, after dupe filtering
100 
-#               igate - igate / client port with user-specified filters
101 
-#               udpsubmit - UDP packet submission port (8080)
102 
-#               dupefeed - duplicate packets dropped by the server
103 
-#       options:
104 
-#               filter "m/500" - force a filter for users connected here
105 
-#               maxclients 100 - limit clients connected on this port
106 
-#               acl etc/client.acl - match client addresses against ACL
107 
-#               hidden - don't show the port in the status page
108 
-#
109 
-#              If you wish to provide UDP service for clients, set up a
110 
-#              second listener on the same address, port and protocol.
111 
-#
112 
-#              The  "::"  is IPv6 "IN6ADDR_ANY", whereas "0.0.0.0" is same
113 
-#              with IPv4.
114 
-#
115 
-#              On FreeBSD you need to have separate listeners for IPv4 and
116 
-#              IPv6. On Linux, just use :: alone - the IPv6 listener will
117 
-#              catch the IPv4 connections just as well.
118 
-#
119 
-# Example of normal server ports for Linux, supporting both TCP and UDP,
120 
-# IPv4 and IPv6:
121 
-#
122 
-Listen "Full feed"                                fullfeed tcp ::  10152 hidden
123 
-Listen ""                                         fullfeed udp ::  10152 hidden
124 
-
125 
-Listen "Client-Defined Filters"                   igate tcp ::  14580
126 
-Listen ""                                         igate udp ::  14580
127 
-
128 
-Listen "350 km from my position"                 igate tcp ::  20350 filter "m/350"
129 
-Listen ""                                        igate udp ::  20350 filter "m/350"

138 
-#               ro   - read-only, do not transmit anything upstream
139 
-#
140 
-# If you wish to specify multiple alternative servers, use multiple
141 
-# Uplink lines, one for each server.
142 
-#
143 
-# Normally a single line for the 'rotate' address is fine - it will connect
144 
-# to one of the servers in a random fashion and go for another one should
145 
-# the first one become unavailable.

-# OPTIONAL: Bind source address before connecting to an uplink

-# You can enter two addresses, one for IPv4 and one for IPv6 connections.

-### HTTP server ##########
158 
-# HTTPStatus port provides a status view to web browsers.
159 
-# IPv6+IPv4 support works slightly differently than in Listen:
160 
-# :: is "all addresses" for IPv6, 0.0.0.0 for IPv4, but
161 
-# :: only works if you actually have a global IPv6 address
162 
-# configured on the system.
163 
-# The example is for IPv4, change the address to :: if you have
164 
-# IPv6. For FreeBSD, or if you wish to support multiple specific
165 
-# ports/addresses, use multiple HTTPStatus directives for each.
166 
-HTTPStatus 0.0.0.0 14501
167 
-# HTTPUpload port allows position uploads over HTTP
168 
-HTTPUpload 0.0.0.0 8080

172 
-# increase several resource limits, and do other things that less privileged
173 
-# server can not do.
174 
-#
175 
-# The FileLimit is resource limit on how many simultaneous connections and
176 
-# some other internal resources the system can use at the same time.

1701 
+ * 🍂class VectorGrid.Protobuf
1702 
+ * 🍂extends VectorGrid
1703 
+ *
1704 
+ * A `VectorGrid` for vector tiles fetched from the internet.
1705 
+ * Tiles are supposed to be protobufs (AKA "protobuffer" or "Protocol Buffers"),
1706 
+ * containing data which complies with the
1707 
+ * [MapBox Vector Tile Specification](https://github.com/mapbox/vector-tile-spec/tree/master/2.1).
1708 
+ *
1709 
+ * This is the format used by:
1710 
+ * - Mapbox Vector Tiles
1711 
+ * - Mapzen Vector Tiles
1712 
+ * - ESRI Vector Tiles
1713 
+ * - [OpenMapTiles hosted Vector Tiles](https://openmaptiles.com/hosting/)
1714 
+ *
1715 
+ * 🍂example
1716 
+ *
1717 
+ * You must initialize a `VectorGrid.Protobuf` with a URL template, just like in
1718 
+ * `L.TileLayer`s. The difference is that the template must point to vector tiles
1719 
+ * (usually `.pbf` or `.mvt`) instead of raster (`.png` or `.jpg`) tiles, and that
1720 
+ * you should define the styling for all the features.
1721 
+ *
1722 
+ * <br><br>
1723 
+ *
1724 
+ * For OpenMapTiles, with a key from [https://openmaptiles.org/docs/host/use-cdn/](https://openmaptiles.org/docs/host/use-cdn/),
1725 
+ * initialization looks like this:
1726 
+ *
1727 
+ * ```
1728 
+ * L.vectorGrid.protobuf("https://free-{s}.tilehosting.com/data/v3/{z}/{x}/{y}.pbf.pict?key={key}", {
1729 
+ * 	vectorTileLayerStyles: { ... },
1730 
+ * 	subdomains: "0123",
1731 
+ * 	key: 'abcdefghi01234567890',
1732 
+ * 	maxNativeZoom: 14
1733 
+ * }).addTo(map);
1734 
+ * ```
1735 
+ *
1736 
+ * And for Mapbox vector tiles, it looks like this:
1737 
+ *
1738 
+ * ```
1739 
+ * L.vectorGrid.protobuf("https://{s}.tiles.mapbox.com/v4/mapbox.mapbox-streets-v6/{z}/{x}/{y}.vector.pbf?access_token={token}", {
1740 
+ * 	vectorTileLayerStyles: { ... },
1741 
+ * 	subdomains: "abcd",
1742 
+ * 	token: "pk.abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRTS.TUVWXTZ0123456789abcde"
