+=======================
+=The Reflex Map Format=
+=======================
+
+Worldspawn contains all brushes and entities.  The maps I've seen contain only a single Worldspawn.
+
+"Pickup" denoted by ID number.  We stored the Reflex to Xonotic conversion in r2x.pck
+
+<Table of ID to their pickup name>
+
+
+"PlayerSpawn" consists of coordinate (Vector3),
+              angle (first element of Vector3), 
+              team indicator (on individual lines), 
+              game type indicator (on individual lines)
+
+-"JumpPad" stored as a brush and a Target
+
+-"Teleporter" stored as a brush and a Target
+
+-"Target" stored as a position (Vector3) and
+                    a "name" (String32)
+          ***Target can be destination of teleports OR jump pads
+
+-"RaceStart" stored as a brush
+
+-"RaceFinish" stored as a brush
+
+That's all we have converted so far but we intend to convert Effect,
+PointLight, Prefab, CameraPath, and possibly liquids.
