debconf-escape -e < unescaped-text
debconf-escape -u < escaped-text
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".
