+makedumpfile can read \fIVMCORE\fR(s) in three kinds of sadump
+formats: single partition format, diskset format and media backup
+format, and can convert each of them into kdump-compressed format with
+filtering and compression processing. Note that for \fIVMCORE\fR(s)
+created by sadump, you always need to pass \fIVMLINUX\fR with -x
+option. Also, to pass multiple \fIVMCORE\fRs created on diskset
+configuration, you need to use --diskset option.
