Add a block device or virtual machine image to the shell.
+The format of the disk image is auto-detected. To override this and
+force a particular format use the I<--format=..> option.

=item B<-c URI> | B<--connect URI>
When used in conjunction with the I<-d> option, this specifies
#!/usr/bin/guestfish -f
+=item B<--format=raw|qcow2|..> | B<--format>
+
+The default for the I<-a> option is to auto-detect the format of the
+disk image. Using this forces the disk format for I<-a> options which
+follow on the command line. Using I<--format> with no argument
+switches back to auto-detection for subsequent I<-a> options.
+
+For example:
+
+ guestfish --format=raw -a disk.img
+
+forces raw format (no auto-detection) for C<disk.img>.
+
+ guestfish --format=raw -a disk.img --format -a another.img
+
+forces raw format (no auto-detection) for C<disk.img> and reverts to
+auto-detection for C<another.img>.
+
+If you have untrusted raw-format guest disk images, you should use
+this option to specify the disk format. This avoids a possible
+security problem with malicious guests (CVE-2010-3851). See also
