r1614: * Patch from Andrew Suffield <asuffield@debian.org> to make dh_strip
support saving the debugging symbols with a --keep-debug flag and
dh_shlibdeps skip /usr/lib/debug. Thanks! Closes: #215670
* Add --dbg-package flag to dh_strip, to list packages that have associated
-dbg packages. dh_strip will then move the debug symbols over to the
associated -dbg packages.
