Little less confusing if I comment here, rather than inline, I think.
Create files named debian/post{rm,inst} and debian/pre{rm,inst} if you
need to add specific code for one package. For multiple debs from same
source create debian/$package.post{rm,inst} debian/$package.pre{rm,inst}
If you use debhelper commands (ie dh_installdocs, dh_isntallman,
dh_installmenu) inside your debian/rules, then at the bottom of your
hand crafted maintainer scripts (debian/[$package]{post,pre}.{rm,inst})
add on a line by itself #DEBHELPER#.
That will cause the dh_scripts to automatically merg code into your hand
crafted scripts before they are installed into
debian/{$package,tmp}/DEBIAN.
For instance, the #DEBHELPER# token causes dh_installdocs to add code to
automatically create a symlink from /usr/share/doc/$package to
/usr/doc/$package and remove it upon package removal.
