+B<dh_makeshlibs> is a debhelper program that automatically scans for shared
libraries, and generates a shlibs file for the libraries it finds.
-It also adds a call to ldconfig in the postinst and postrm scripts (in

+Packages that support multiarch are detected, and

+you should make sure to put that token into an appropriate place in your

information, the current upstream version of the package is plugged into a

-debhelper compatibility levels before v4, the debian part of the package
