+L<guestfish(1)> is a more powerful, lower level tool which you can use
+when C<virt-cat> doesn't work.
+
+Using C<virt-cat> is approximately equivalent to doing:
+
+ guestfish --ro -i -d domname download file -
+
+where C<domname> is the name of the libvirt guest, and C<file> is the
+full path to the file.  Note the final C<-> (meaning "output to
+stdout").
+
+The command above uses libguestfs's guest inspection feature and so
+does not work on guests that libguestfs cannot inspect, or on things
+like arbitrary disk images that don't contain guests.  To display a
+file from a disk image directly, use:
+
+ guestfish --ro -a disk.img -m /dev/sda1 download file -
+
+where C<disk.img> is the disk image, C</dev/sda1> is the filesystem
+within the disk image to edit, and C<file> is the full path to the
+file.
