+=head1 NAME
+
+TAP::Parser::Iterator::Array - Internal TAP::Parser array Iterator
+
+=head1 VERSION
+
+Version 3.12
+
+=cut
+
+$VERSION = '3.12';
+
+=head1 SYNOPSIS
+
+  # see TAP::Parser::IteratorFactory for preferred usage
+
+  # to use directly:
+  use TAP::Parser::Iterator::Array;
+  my @data = ('foo', 'bar', baz');
+  my $it   = TAP::Parser::Iterator::Array->new(\@data);
+  my $line = $it->next;
+
+=head1 DESCRIPTION
+
+This is a simple iterator wrapper for arrays of scalar content, used by
+L<TAP::Parser>.  Unless you're subclassing, you probably won't need to use
+this module directly.
+
+=head1 METHODS
+
+=head2 Class Methods
+
+=head3 C<new>
+
+Create an iterator.  Takes one argument: an C<$array_ref>
+
+=head2 Instance Methods
+
+=head3 C<next>
+
+Iterate through it, of course.
+
+=head3 C<next_raw>
+
+Iterate raw input without applying any fixes for quirky input syntax.
+
+=head3 C<wait>
+
+Get the wait status for this iterator. For an array iterator this will always
+be zero.
+
+=head3 C<exit>
+
+Get the exit status for this iterator. For an array iterator this will always
+be zero.
