NAME
       dh_makeshlibs - automatically create shlibs file

SYNOPSIS
       dh_makeshlibs [debhelper options] [-mmajor] [-V[dependencies]] [-n]
       [-Xitem]

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 which it finds shared libraries
       in.

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 ver
	   sion number), so that if the maintainer screws up then they wont
	   break. The flip side is that packages might end up with dependen
	   cies 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.

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)
