+# The format converter is responsible for the storage domains'
+# version maintenancy.
+#
+# A storage domain's version reflects its meta data compatibility,
+# for example, data storage domain should be supported for version 3 and 4.
+#
+# The FormatConverter is mainly being used on upgrade process, for example
+# a 4.1 Data Center should be supported only with V4 storage domains.
+#
+# Version 4 should eventualy reflect support for old and new
+# qcow formats, 0.10 and 1.1.
