 from the fragments.
 
+By instead using the \fB-overlay:\fIlist\fR argument where \fIlist\fR
+is a colon-separated list of filenames, \fBfusefile\fR will use those
+as an ordered stack of overlays and "inject" them as fragments on top
+of each other.

 The option \fB-dump\fR as first argument together with a fusefile
 setup will print the setup to standard output rather than establishing
-a fusefile mount. This is of most use with a prior overlay setup,

 fragment argments to give in order to intersperse the captured overlay
 portions according to the overlay table.
 
+The option \fB-push\fR as first argument together with a fusefile

+write-protected fragments). This is only of use with a prior overlay

 \fBfusedisk\fR is a helper script to set up a \fBfusefile\fR as a
 block device (via \fIfuseblk\fR) by using the device mapper
 (\fBdmsetup\fR) to manage an empty block device mapping where content
