+=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 help | 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
+
+=head1 PROGRESS BARS
+
+Some (not all) long-running commands send progress notification
+messages as they are running. Guestfish turns these messages into
+progress bars.
+
+When a command that supports progress bars takes longer than two
+seconds to run, and if progress bars are enabled, then you will see
+one appearing below the command:
+
+ ><fs> copy-size /large-file /another-file 2048M
+ / 10% [#####-----------------------------------------] 00:30
+
+The spinner on the left hand side moves round once for every progress
+notification received from the backend. This is a (reasonably) golden
+assurance that the command is "doing something" even if the progress
+bar is not moving, because the command is able to send the progress
+notifications. When the bar reaches 100% and the command finishes,
+the spinner disappears.
+
+Progress bars are enabled by default when guestfish is used
+interactively. You can enable them even for non-interactive modes
+using I<--progress-bars>, and you can disable them completely using
+I<--no-progress-bars>.
