     The second form lists the detailed help information for a specific

+    The third form enumerates all the available --sources (source
+    plugins).  The contents of a given partition are driven by code
+    defined in 'source plugins'.  Users specify a specific plugin via
+    the --source parameter of the partition .wks command.  Normally
+    this is the 'rootfs' plugin but can be any of the more specialized
+    sources listed by the 'list source-plugins' command.  Users can
+    also add their own source plugins - see 'wic help plugins' for
