+Swallow (XMP-16) ethernet loader
+.......
+
+:Version:  0.0.1
+
+:Status:  Alpha
+
+:Maintainer:  https://github.com/stevekerrison
+
+:Description:  Implements an Ethernet peripheral to allow network booting of a Swallow compute grid.
+
+
+Key Features
+============
+
+* Uses module_swallow_xlinkboot to initialise a network of Swallow boards
+* Uses the XMOS ethernet stack to provide a mechanism for network booting cores
+* Can also provide ethernet based data I/O
+
+To Do
+=====
+
+* Lots, see commit logs and comments
