=head1 DESCRIPTION
dh_shlibdeps is a debhelper program that is responsible for calculating
-shared library dependancies for packages.
+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 control file, passing it
=item B<-X>I<item>, B<--exclude=>I<item>
Exclude files that contain "item" anywhere in their filename from being
-passed to dpkg-shlibdeps. This will make their dependancies be ignored.
+passed to 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<-l>I<directory>[:directory:directory:..]
-Before dpkg-shlibdeps is run, LD_LIBRARY_PATH will have added to it the
-specified directory (or directories -- separate with colons). This is
-useful for multi-binary packages where a library is built in one
-package and another package contains binaries linked against said
-library. Relative paths will be made absolute for the benefit of
-dpkg-shlibdeps.
+With recent versions of dpkg-shlibdeps, this option is generally not
+needed.
-Note that the directory given should be the complete or relative path to
-a directory that contains the library. See example below.
+Before dpkg-shlibdeps is run, LD_LIBRARY_PATH will have added to it the
+specified directory (or directories -- separate with colons). With recent
+versions of 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>
-Use the shlibs file automatically generated by dh_makeshlibs for the named
-package as a kind of automatically generated shlibs.local file. You can use
-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.
+With recent versions of dpkg-shlibdeps, this option is generally not
+needed, unless your package builds multiple flavors of the same library.
+
+It tells dpkg-shlibdeps (via its -S parameter) to look first in the package
+build directory for the specified package, when searching for libraries,
+symbol files, and shlibs files.

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
+ 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
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 /usr/lib/bar/, you can make libfoo-bin depend
+on libbar1 as follows:
+
+ dh_shlibdeps -Llibbar1 -l/usr/lib/bar
