+=head1 NAME
+
+guestfs-python - How to use libguestfs from Python
+
+=head1 SYNOPSIS
+
+ import guestfs
+ g = guestfs.GuestFS ()
+ g.add_drive_opts ("disk.img", format="raw", readonly=1)
+ g.launch
+
+=head1 DESCRIPTION
+
+This manual page documents how to call libguestfs from the Python
+programming language. This page just documents the differences from
+the C API and gives some examples. If you are not familiar with using
+libguestfs, you also need to read L<guestfs(3)>.
+
+=head2 EXCEPTIONS
+
+Errors from libguestfs functions are mapped into C<RuntimeException>
+with a single string argument which is the error message.
+
+=head2 MORE DOCUMENTATION
+
+Type:
+
+ $ python
+ >>> import guestfs
+ >>> help (guestfs)
