NAME
       dh_makeshlibs - automatically create shlibs file and call dpkg-gensymbols

SYNOPSIS
       dh_makeshlibs [debhelperoptions] [-mmajor] [-V[dependencies]] [-n] [-Xitem] [--params]

DESCRIPTION
       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 v3 mode and above
       only) to any packages in which it finds shared libraries.

       Packages that support multiarch are detected, and a Pre-Dependency on multiarch-support is
       set in ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate
       place in your debian/control file for packages supporting multiarch.

FILES
       debian/package.symbols
       debian/package.symbols.arch
	   These symbols files, if present, are passed to dpkg-gensymbols(1) to be processed and
	   installed. Use the arch specific names if you need to provide different symbols files
	   for different architectures.

OPTIONS
       -mmajor, --major=major
	   Instead of trying to guess the major number of the library with objdump, use the major
	   number specified after the -m parameter. This is much less useful than it used to be,
	   back in the bad old days when this program looked at library filenames rather than
	   using objdump.

       -V, -Vdependencies
       --version-info, --version-info=dependencies
	   By default, the shlibs file generated by this program does not make packages depend on
	   any particular version of the package containing the shared library. It may be
	   necessary for you to add some version dependancy information to the shlibs file. If -V
	   is specified with no dependency information, the current upstream version of the
	   package is plugged into a dependency that looks like "packagename (>=
	   packageversion)". Note that in debhelper compatibility levels before v4, the Debian
	   part of the package version number is also included. If -V is specified with
	   parameters, the parameters can be used to specify the exact dependency information
	   needed (be sure to include the package name).

	   Beware of using -V without any parameters; this is a conservative setting that always
	   ensures that other packages' shared library dependencies are at least as tight as they
	   need to be (unless your library is prone to changing ABI without updating the upstream
	   version number), so that if the maintainer screws up then they won't break. The flip
	   side is that packages might end up with dependencies that are too tight and so find it
	   harder to be upgraded.

       -n, --noscripts
	   Do not modify postinst/postrm scripts.

       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename or directory from being
	   treated as shared libraries.

       --add-udeb=udeb
	   Create an additional line for udebs in the shlibs file and use udeb as the package
	   name for udebs to depend on instead of the regular library package.

       -- params
	   Pass params to dpkg-gensymbols(1).

EXAMPLES
       dh_makeshlibs
	   Assuming this is a package named libfoobar1, generates a shlibs file that looks
	   something like:
	    libfoobar 1 libfoobar1

       dh_makeshlibs -V
	   Assuming the current version of the package is 1.1-3, generates a shlibs file that
	   looks something like:
	    libfoobar 1 libfoobar1 (>= 1.1)

       dh_makeshlibs -V 'libfoobar1 (>= 1.0)'
	   Generates a shlibs file that looks something like:
	     libfoobar 1 libfoobar1 (>= 1.0)
