+=head1 NAME
+
+virt-edit - Edit a file in a virtual machine
+
+=head1 SYNOPSIS
+
+ virt-edit [--options] domname file
+
+ virt-edit [--options] disk.img [disk.img ...] file
+
+=head1 DESCRIPTION
+
+C<virt-edit> is a command line tool to edit C<file> where C<file>
+exists in the named virtual machine (or disk image).
+
+B<Note> you must I<not> use virt-edit on live virtual machines. If
+you do this, you risk disk corruption in the VM.
+
+If you want to just view a file, use L<virt-cat(1)>. For more complex
+cases you should look at the L<guestfish(1)> tool.
+
+=head1 EXAMPLES
+
+ virt-edit mydomain /boot/grub/grub.conf
+
+ virt-edit mydomain /etc/passwd
