=head1 DESCRIPTION
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
-DH_COMPAT=3 mode and above only).
+DH_COMPAT=3 mode and above only) to any packages which it finds shared
+libraries in.
=head1 OPTIONS
library. It may be necessary for you to add some version dependancy
information to the shlibs file. If -V is specified with no dependancy
information, the current version of the package is plugged into a
-dependancy that looks like "packagename (>= packageversion)". If -V is specified with
-parameters, the parameters can be used to specify the exact dependancy
-information needed (be sure to include the package name).
+dependancy that looks like "packagename (>= packageversion)". If -V is
+specified with parameters, the parameters can be used to specify the exact
+dependancy 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, 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.
