+ * dh: Now you can use override_dh_command-arch and override_dh_command-indep
+ to run different overrides when building arch and indep packages. This
+ allows for a much simplified form of rules file in this situation, where
+ build-arch/indep and binary-arch/indep targets do not need to be manually
+ specified. See man page for examples. Closes: #640965
+ * dh: Note that if a rules file has say, override_dh_fixperms-arch,
+ but no corresponding override_dh_fixperms-indep, then the unoverridden
+ dh_fixperms will be run on the indep packages.
+ * dh: Note that the old override_dh_command takes precidence over the new
+ overrides, because mixing the two types of overrides would have been
+ too complicated. In particular, it's difficult to ensure an
+ old override target will work if it's sometimes constrained to only
+ acting on half the packages it would normally run on. This would be
+ a source of subtle bugs, so is avoided.
