+# generate shlibs/symbols files for samba packages
+#
+# samba ships a mix of:
+# public libraries with stable ABI in /usr/lib
+# public libraries in /usr/lib
+# public python libraries in /usr/lib
+# private libraries in /usr/lib/samba/
+# plugins in /usr/lib/samba/*/
+#
+# For public libraries with stable ABI we generate symbols files.
+# These are listed in d/package.symbols files.
+# For other librries, we only need to generate shlibs files
+# with basic version information so that dpkg-shlibdeps will find them.
+# Here, for libs without .symbols file, we have 2 choices:
+# for public libraries we generate ($pkg >> $version) dependency in
+# shlibs file, but for private libs the relation is equality (=).
+# We do not process plugins, and we do not process python objects.
+#
+# dh_makeshlibs is too difficult to use here, we have much simpler approach.
+# We know exactly where our libs resides (dh_makeshlibs looks everywhere)
+# and we know filename patterns to recognize our shared libs.
+# dh_makeshlibs can not be used to generate symbols files for *some* libraries
+# (it is either all if .symbols is provided, or nothing if not).
+# It is easier to take strightforward approach than to fight a tool.
