=head1 NAME

Dpkg::Vendor::Default - default vendor object

=head1 DESCRIPTION

A vendor object is used to provide vendor specific behaviour
in various places. This is the default object used in case
there's none for the current vendor or in case the vendor could
not be identified (see Dpkg::Vendor documentation).

It provides some hooks that are called by various dpkg-* tools.
If you need a new hook, please file a bug against dpkg-dev and explain
your need. Note that the hook API has no guaranty to be stable over an
extended period. If you run an important distribution that makes use
of vendor hooks, you'd better submit them for integration so that
we avoid breaking your code.

=head1 FUNCTIONS

=over 4

=item $vendor_obj = Dpkg::Vendor::Default->new()

Creates the default vendor object. Can be inherited by all vendor objects
if they don't need any specific initialization at object creation time.

sub new {
    my ($this) = @_;
    my $class = ref($this) || $this;
    my $self = {};
    bless $self, $class;
    return $self;
}

=item $vendor_obj->run_hook($id, @params)

Run the corresponding hook. The parameters are hook-specific. The
supported hooks are:

=over 8

=item before-source-build ($srcpkg)

The first parameter is a Dpkg::Source::Package object. The hook is called
just before the execution of $srcpkg->build().

=item before-changes-creation ($fields)

The hook is called just before the content of .changes file is output
by dpkg-genchanges. The first parameter is a Dpkg::Fields::Object
representing all the fields that are going to be output.
