+
+Use the shlibs file automatically generated by dh_makeshlibs for the named
+package as a kind of automatically generated shlibs.local file. You can us
+this switch in concert with the -l switch to make dpkg-shlibdeps find a
+library built as part of the current package, and get the shlibs information.
+See example below.

+=head1 EXAMPLES
+
+Suppose that your source package produces libfoo1, libfoo-dev, and
+libfoo-bin binary packages. libfoo-bin links against libfoo, and should
+depend on it. In your rules file, first run dh_makeshlibs, then dh_shlibdeps:
+
+	dh_makeshlibs
+	dh_shlibdeps -L libfoo1 -l debian/libfoo1/usr/lib
+
+This will have the effect of generating automatically a shlibs file for
+libfoo1, and using that file and the libfoo1 library in the
+debian/libfoo1/usr/lib directory to calculate shared library dependency
+information.
