+This page describes the Farsight2 coding style. Respect it or die.
+
+It is a copy of
+http://farsight.freedesktop.org/wiki/Fs2CodingStyle
+
+They should both be in sync
+
+
+
+Loosely based on GNU style C.
+
+Max line width 80.
+
+All long lines wrapped with 4 space indentation.
+
+Spaces after all procedural calls (includes macros).
+
+Function names and variables names use underscore word separators. All GObject methods are prefixed with the appropriate prefix for the object.
+
+Typenames are in camelcase.
+
+NO TABS!
+
+Base indent unit is 2 spaces.
+
+==== Function prototypes ====
+
+The first parameter is on the same line as the function only if the function is a method.
+
+static void farsight_rtp_stream_get_property (GObject *object,
+    guint prop_id,
+    GValue *value,
+    GParamSpec *pspec);
+
+==== Function declarations ====

+The first parameter is on the same line as the function only if the function is a method.
+
+static void 
+farsight_rtp_stream_get_property (GObject * object,
+    guint prop_id,
+    GValue * value,
+    GParamSpec * pspec)
+{
+}
+
+==== If/else/while/for/do/struct/switch/etc ====
+
+if (condition)
+{
+  die ();
+}
+else
+{
+  die ();
+}
+
+For blocks that only contain one statement, the opening/closing brackets can be omitted. But this can only be done if all the blocks in a statement contain only one statement. This is an ILLEGAL example :
+
+if (condition)
+  die ();
+else
+{
+  die ();
+  die_again ();
+}
+
+
+==== Breaks and boolean operators ====
+
+if (self->priv->main_pipeline && src_in_pipeline
+    || !self->priv->your_mama)
+{
+}
+
+==== Pointer declarations ====
+
+Type *var;
+
+==== Switch ====
+
+switch (var)
+{
+  case 4:
+    die ();
+    break;
+  case 5:
+    die ();
+}
+
+==== Casting ====
+
+FarsightRTPStream *self = (FarsightRTPStream *) stream;
+
+==== Emacs mode ====
+
