+ Server address resolution
+
+The libdcui library implements a rather flexible scheme for resolving
+the adress of the server to connect to. In order for you to be able to
+create the setup you would like best, this file documents the
+scheme. It is worth noting that it is implemented in the library
+itself, and so is automatically shared by any program using it,
+including (but not limited to) dolcon, autodl, hubmgr, the panel
+applet, Pidgin plugin and others.
+
+The server address is specified as a single string. If no server has
+been explicity specified, the library first checks the environment
+variable DCSERVER, and uses its value if set. If it is unset as well,
+the library attempts the following connections, in order:
+
+ * The Unix socket /tmp/doldacond-$USERNAME
+ * The Unix socket /var/run/doldacond.sock
+ * TCP port 1500 on localhost
+ * If compiled with DNS support and getdomainname(2) does not return
+ `(none)' or nothing, the address indicated by the _dolcon._tcp SRV
+ record on that domain, if one exists.
+
+If a server is specified, either explicity or through the DCSERVER
+environment variable, it is resolved as follows:
+
+ * If the address contains a slash character, it is assumed to be the
+ name of a Unix socket.
+ * If the address does not contain a colon, and the library has been
+ compiled with DNS support, and the address specifies a domain name
+ with a _dolcon._tcp SRV record, the address of that SRV record is
+ used.
+ * If the address matches the regexp `^\[(.*)\]:([0-9]+)$', the string
+ in the first subgroup is resolved by the system's getaddrinfo(3),
+ and the port set to the second subgroup, and the result is
+ connected to. This is mostly intended for connecting to literal
+ IPv6 addresses.
+ * If none of the above rules have been matched, the address
+ specification is resolved using the system's getaddrinfo(3)
+ implementation, and connected to. A port number can be specified by
+ appending a colon and the port number to the address specification,
+ such as in `localhost:1500'.
+ * If none of the above rules are successful, the connection fails.
