+=head1 PREPARED DISK IMAGES
+
+Use the I<-N type> or I<--new type> parameter to select one of a set
+of preformatted disk images that guestfish can make for you to save
+typing. This is particularly useful for testing purposes. This
+option is used instead of the I<-a> option, and like I<-a> can appear
+multiple times (and can be mixed with I<-a>).
+
+The new disk is called C<test1.img> for the first I<-N>, C<test2.img>
+for the second and so on. Existing files in the current directory are
+I<overwritten>.
+
+The type briefly describes how the disk should be sized, partitioned,
+how filesystem(s) should be created, and how content should be added.
+Optionally the type can be followed by extra parameters, separated by
+C<:> (colon) characters. For example, I<-N fs> creates a default
+100MB, sparsely-allocated disk, containing a single partition, with
+the partition formatted as ext2. I<-N fs:ext4:1G> is the same, but
+for an ext4 filesystem on a 1GB disk instead.
+
+To list the available types and any extra parameters they take, run:
+
+ guestfish -N list | less
+
+Note that the prepared filesystem is not mounted. You would usually
+have to use the C<mount /dev/sda1 /> command or add the
+I<-m /dev/sda1> option.
+
+If any I<-N> or I<--new> options are given, the guest is automatically
+launched.

+=head2 EXAMPLES
+
+Create a 100MB disk with an ext4-formatted partition:
+
+ guestfish -N fs:ext4
+
+Create a 32MB disk with a VFAT-formatted partition, and mount it:
+
+ guestfish -N fs:vfat:32M -m /dev/sda1
+
+Create a blank 200MB disk:
+
+ guestfish -N disk:200M
