+=head1 NAME
+
+Lintian::Processable::Installable::Class - Lintian interface to binary package data collection
+
+=head1 SYNOPSIS
+
+    my ($name, $type, $dir) = ('foobar', 'binary', '/path/to/lab-entry');
+    my $collect = Lintian::Processable::Installable::Class->new($name);
+
+=head1 DESCRIPTION
+
+Lintian::Processable::Installable::Class provides an interface to package data for binary
+packages.
+
+=head1 INSTANCE METHODS
+
+=over 4
+
+=item is_debug_package
+
+The package probably contains only debug symbols.
+
+=cut
+
+sub is_debug_package {
+    my ($self) = @_;
+
+    return 1
+      if $self->name =~ /-dbg(?:sym)?/;
+
+    return 0;
+}
+
+=item is_auto_generated
+
+The package was probably generated automatically.
+
+=cut
+
+sub is_auto_generated {
+    my ($self) = @_;
+
+    return 1
+      if $self->fields->declares('Auto-Built-Package');
+
+    return 0;
+}
+
+=item is_transitional
+
+The package is probably transitional, i.e. it probably depends
+ on stuff will eventually disappear.
+
+=cut
+
+sub is_transitional {
+    my ($self) = @_;
+
+    return 1
+      if $self->fields->value('Description') =~ /transitional package/i;
+
+    return 0;
+}
+
+=item is_meta_package
+
+This package is probably some kind of meta or task package.  A meta
+package is usually empty and just depend on stuff.  It also returns
+a true value for "tasks" (i.e. tasksel "tasks").
+
+=cut
+
+sub is_meta_package {
+    my ($self) = @_;
+
+    return 1
+      if $self->fields->value('Description')
+      =~ /meta[ -]?package|(?:dependency|dummy|empty) package/i;
+
+    # section "tasks" or "metapackages" qualifies too
+    return 1
+      if $self->fields->value('Section') =~ m{(?:^|/)(?:tasks|metapackages)$};
+
+    return 1
+      if $self->name =~ /^task-/;
+
+    return 0;
