=head1 INSTALLING
=head2 Debian Jessie or older
is to build the package for all the architectures you
have enabled.
You'll need a chroot for each of the secondary architectures.

-C<sbuild-createchroot> from the sbuild package is a

+C<sbuild-debian-developer-setup> from the package of the same name
+and C<sbuild-createchroot> from the C<sbuild> package are

Otherwise you could deinstall the packages of interest
for those other architectures
your desperate last resort is to try
using the same version number
as the official package for your own package.

This is not ideal because it makes it hard to tell what is installed,
and because it will mislead and confuse apt.
