description

When debconf has the ’escape’ capability set, it will expect commands you send it to have backslashes and newlines escaped (as "\\" and "\n" respectively) and will in turn escape backslashes and newlines in its replies. This can be used, for example, to substitute multi-line strings into templates, or to get multi-line extended descriptions reliably using "METAGET".
