Ah, so you then need to have #DEBHELPER# lines in your scripts.

And, if necessary, preinst and prerm.  Have a look at which scripts
debhelper creates (like postinst.debhelper) in the debian/ directory.

Yes, either that or at the end.  Or somewhere else.
Have a look at section 6 of the packaging manual which explains how
