blank_after_changes => [],
blank_after_trailer => [],
};
bless $self, $class;
return $self;
}
=item $str = $entry->output()
=item "$entry"
Get a string representation of the changelog entry.
=item $entry->output($fh)
Print the string representation of the changelog entry to a
filehandle.

=item $entry->get_part($part)
Return either a string (for a single line) or an array ref (for multiple
lines) corresponding to the requested part. $part can be
"header, "changes", "trailer", "blank_after_header",
"blank_after_changes", "blank_after_trailer".

}
=item $entry->set_part($part, $value)
Set the value of the corresponding part. $value can be a string
or an array ref.

}
=item $entry->extend_part($part, $value)
Concatenate $value at the end of the part. If the part is already a
multi-line value, $value is added as a new line otherwise it's
concatenated at the end of the current line.
