+=head1 NAME
+
+Sys::Guestfs - Perl bindings for libguestfs
+
+=head1 SYNOPSIS
+
+ use Sys::Guestfs;
+
+ my $h = Sys::Guestfs->new ();
+ $h->add_drive ('guest.img');
+ $h->launch ();
+ $h->wait_ready ();
+ $h->mount ('/dev/sda1', '/');
+ $h->touch ('/hello');
+ $h->sync ();
+
+=head1 DESCRIPTION
+
+The C<Sys::Guestfs> module provides a Perl XS binding to the
+libguestfs API for examining and modifying virtual machine
+disk images.
+
+Amongst the things this is good for: making batch configuration
+changes to guests, getting disk used/free statistics (see also:
+virt-df), migrating between virtualization systems (see also:
+virt-p2v), performing partial backups, performing partial guest
+clones, cloning guests and changing registry/UUID/hostname info, and
+much else besides.
+
+Libguestfs uses Linux kernel and qemu code, and can access any type of
+guest filesystem that Linux and qemu can, including but not limited
+to: ext2/3/4, btrfs, FAT and NTFS, LVM, many different disk partition
+schemes, qcow, qcow2, vmdk.
+
+Libguestfs provides ways to enumerate guest storage (eg. partitions,
+LVs, what filesystem is in each LV, etc.). It can also run commands
+in the context of the guest. Also you can access filesystems over FTP.
+
+=head1 ERRORS
+
+All errors turn into calls to C<croak> (see L<Carp(3)>).
