-## === the chain of command ===
-## debuild runs a chain of dh functions in the following order:
-## dh_testdir
-## dh_clean
-## dh_auto_clean
-## dh_update_autotools_config
-## dh_autoreconf
-## dh_auto_configure
-## dh_prep
-## dh_build
-## dh_auto_build
-## dh_install
-## dh_auto_install
-## dh_installdocs
-## dh_installchangelogs
-## dh_perl
-## dh_link
-## dh_strip_nondeterminism
-## dh_compress
-## dh_fixperms
-## dh_missing
-## dh_dwz
-## dh_strip
-## dh_makeshlibs
-## dh_shlibdeps
-## dh_installdeb
-## dh_gencontrol
-## but you are most likely to only need to override the following:
-## dh_clean
-## dh_auto_configure
-## dh_build
-## dh_install

-## === overriding dh functions ===
-## by default all dh functions will run a specific command based on the build system selected by "dh $@"
-## if you have a makefile that does everything you need this is fine,
-## but most likely you have no MakeFile and you want to add your own commands
-## Note : overrides must be places above %:
-## So here's a few examples:
-
-## overriding dh_clean to make it not delete rust vendor files:
-#override_dh_clean:
-#	echo "disabled"
-
-## overriding dh_auto_configure to add custom configs:
-#override_dh_auto_configure:
-#		$(srcdir)/configure -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_DATADIR=/usr/share -DCMAKE_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu -DBUILD_PLUGIN=OFF
-
-## overriding dh_install to install files to a package:
-#override_dh_auto_configure:
-#		mkdir -p debian/pikman/usr/bin
-#		cp pikman debian/pikman/usr/bin/
