+	  Path to custom RCW source files. You can provide a
+	  list of rcw paths to copy and build, separated by spaces.
+	  NOTE: If you want to build one common rcw file
+	  (e.g. "X.rcwi") with main rcw file (e.g. "Y.rcw") then
+	  include common rcw file X.rcwi in main rcw file Y.rcw
+	  using "#include"
+
+	  Do not use ".rcw" suffix for common rcw file(s) because this
+	  tool will compile the .rcw into a binary image.
+
+	  This is optional. If left empty, the RCW package will be
+	  included for use in the SDK or with post scripts but the
+	  binary will not be generated.
