+Image properties with special meaning
+=====================================
+
+Properties used during image deployment
+---------------------------------------
+ - OSFAMILY={linux, windows}
+     This specifies whether this is a Linux or a Windows image.
+ - ROOT_PARTITION=n
+     The partition number of the root partition.
+ - USERS="username1 username2..."
+     This is a space-seperated list of users, whose password will
+     be reset during deployment.
+ - SWAP=<n>:<size>
+     If this property is present, cyclades will create a swap
+     partition with given size at the end of the instance's disk.
+     This property only makes sense for Linux images.
+
+Properties used by the ~okeanos User Interface
+----------------------------------------------
+ - OS
+     The value of this property is used to associate the image
+     with an Operating System Logo.
+ - DESCRIPTION
+     A short description about the image.
+ - SIZE
+     This is used by the UI to compute the image copy progress
+     during deployment.
+ - GUI
+     Short description about the Graphical User Interface the
+     image hosts.
+ - KERNEL
+     The kernel version of the image OS.
