=head1 NAME

Module::CPANTS::Kwalitee::BrokenInstaller - Check for broken Module::Install

=head1 SYNOPSIS

Find out whether the distribution uses an outdated version of Module::Install.

=head1 DESCRIPTION

=head2 Methods

=head3 order

Defines the order in which Kwalitee tests should be run.

Returns C<100>, as data generated by this should not be
used by any other tests.

=head3 analyse

C<MCK::BrokenInstaller> checks whether the distribution uses Module::Install
and if so whether it uses a reasonably current version of it (0.61 or later).

It also checks whether the F<Makefile.PL> uses the C<auto_install> feature.
If so, C<Module::Install> should be at least version 0.64.

=head3 kwalitee_indicators

Returns the Kwalitee Indicators data structure.
