+B<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.
+It also adds a call to ldconfig in the F<postinst> and F<postrm> scripts (in
+v3 mode and above only) to any packages in which it finds shared libraries.
-If a L<dpkg-gensymbols(1)> symbol file is found in debian/package.symbols
-(or debian/package.symbols.arch), dpkg-gensymbols will be called
-to process and install the symbols file.

+Instead of trying to guess the major number of the library with /postobjdump,
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.
By default, the shlibs file generated by this program does not make packages

library. It may be necessary for you to add some version dependancy
