-Use the shlibs file automatically generated by dh_makeshlibs for the named

 This will have the effect of generating automatically a shlibs file for
 libfoo1, and using that file and the libfoo1 library in the
 debian/libfoo1/usr/lib directory to calculate shared library dependency
 information.
 
+If a libbar1 package is also produced, that is an alternate build of
