+=head1 SYNOPSIS
+
+B<dh_shlibdeps> [S<I<debhelper options>>] [B<-L>I<package>] [B<-l>I<directory>] [B<-X>I<item>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+B<dh_shlibdeps> is a debhelper program that is responsible for calculating
+shared library dependencies for packages.
+
+This program is merely a wrapper around L<dpkg-shlibdeps(1)> that calls it
+once for each package listed in the F<control> file, passing it
+a list of ELF executables and shared libraries it has found.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain F<item> anywhere in their filename from being
+passed to B<dpkg-shlibdeps>. This will make their dependencies be ignored.
+This may be useful in some situations, but use it with caution. This option
+may be used more than once to exclude more than one thing.
+
+=item B<--> I<params>
+
+Pass I<params> to L<dpkg-shlibdeps(1)>.
+
+=item B<-u>I<params>, B<--dpkg-shlibdeps-params=>I<params>
+
+This is another way to pass I<params> to L<dpkg-shlibdeps(1)>.
+It is deprecated; use B<--> instead.
+
+=item B<-l>I<directory>[B<:>I<directory> ...]
+
+With recent versions of B<dpkg-shlibdeps>, this option is generally not
+needed.
+
+It tells B<dpkg-shlibdeps> (via its B<-l> parameter), to look for private
+package libraries in the specified directory (or directories -- separate
+with colons). With recent
+versions of B<dpkg-shlibdeps>, this is mostly only useful for packages that
+build multiple flavors of the same library, or other situations where
+the library is installed into a directory not on the regular library search
+path.
+
+=item B<-L>I<package>, B<--libpackage=>I<package>
+
+With recent versions of B<dpkg-shlibdeps>, this option is generally not
+needed, unless your package builds multiple flavors of the same library
+or is relying on F<debian/shlibs.local> for an internal library.
+
+It tells B<dpkg-shlibdeps> (via its B<-S> parameter) to look first in the package
+build directory for the specified package, when searching for libraries,
+symbol files, and shlibs files.
+
+If needed, this can be passed multiple times with different package
+names.
+

+
+=head1 EXAMPLES
+
+Suppose that your source package produces libfoo1, libfoo-dev, and
+libfoo-bin binary packages. libfoo-bin links against libfoo1, and should
+depend on it. In your rules file, first run B<dh_makeshlibs>, then B<dh_shlibdeps>:
+
+	dh_makeshlibs
+	dh_shlibdeps
+
+This will have the effect of generating automatically a shlibs file for
+libfoo1, and using that file and the libfoo1 library in the
+F<debian/libfoo1/usr/lib> directory to calculate shared library dependency
+information.
+
+If a libbar1 package is also produced, that is an alternate build of
+libfoo, and is installed into F</usr/lib/bar/>, you can make libfoo-bin depend
+on libbar1 as follows:
+
+	dh_shlibdeps -Llibbar1 -l/usr/lib/bar
+
