+=head1 NAME
+
+virt-cat - Display a file in a virtual machine
+
+=head1 SYNOPSIS
+
+ virt-cat [--options] domname file
+
+ virt-cat [--options] disk.img [disk.img ...] file
+
+=head1 DESCRIPTION
+
+C<virt-cat> is a command line tool to display the contents of C<file>
+where C<file> exists in the named virtual machine (or disk image).
+
+C<virt-cat> can be used to quickly view a single file. For more
+complex cases you should look at the L<guestfish(1)> tool.
+
+=head1 EXAMPLES
+
+Display C</etc/fstab> file from inside the libvirt VM called
+C<mydomain>:
+
+ virt-cat mydomain /etc/fstab
+
+List syslog messages from a VM:
+
+ virt-cat mydomain /var/log/messages | tail
+
+Find out what packages were recently installed:
+
+ virt-cat mydomain /var/log/yum.log | tail
+
+Find out who is logged on inside a virtual machine:
+
+ virt-cat mydomain /var/run/utmp > /tmp/utmp
+ who /tmp/utmp
+
+or who was logged on:
+
+ virt-cat mydomain /var/log/wtmp > /tmp/wtmp
+ last -f /tmp/wtmp
+

+If you specify guest block devices directly, then libvirt is not used
