# @tcp: host address and port number
#
+# This is similar to SocketAddress, only distinction:
+#
+# 1. GlusterServer is a flat union, SocketAddress is a simple union.
+# A flat union is nicer than simple because it avoids nesting
+# (i.e. more {}) on the wire.
+#
+# 2. GlusterServer lacks case 'fd', since gluster doesn't let you
+# pass in a file descriptor.
+#
+# GlusterServer is actually not Gluster-specific, its a
+# compatibility evolved into an alternate for SocketAddress.
+#
# Since: 2.7
