+# On SuSE 9 no separate "debuginfo" package is built. To enable basic
+# debugging on that platform, we don't strip binaries on SuSE 9. We
+# disable the strip of binaries by redefining the RPM macro
+# "__os_install_post" leaving out the script calls that normally does
+# this. We do this in all cases, as on platforms where "debuginfo" is
+# created, a script "find-debuginfo.sh" will be called that will do
+# the strip anyway, part of separating the executable and debug
+# information into separate files put into separate packages.
