+		Comment:
+			This script builds once a day and ultimately publishes the build.
+
+			For the moment, it's intended to run on trunk.  However the design
+			can be "tweaked" to publish to builds/$JOBNAME/Daily etc
+
+			I don't want to run this on code submission as I think we're going to
+			get it to build all 12 Visual Studio builds (2005/2008/2010/2012/2013/2015) 32/64
+			This will take about 1 hour on the build server.  Not something to be done frequently.
+
+			We could modify this to build on MSVC 2013 when triggered by SVN, else MSVC=all for time triggered
+			And we could offer a UI for user selection of MSVC builds
+
+			Currently MinGW has not been implemented.
+
+			There are three quite different parts of the script:
+			1) Use CMake to build on each platform using cmake_daily.sh
+			2) Validate each platform using test_daily.sh
+			3) Categorize the build (create links for Platform/SVN/Date/Latest)
+
+			At the moment, the "pruning" of the builds is performed by cmake_daily.sh
+			The "pruning" code will probably move to categorize.sh
