+How to analyze coverage:
+1. gbs build adding --define '_with_coverage 1'
+2. take *.o and *.gcno files from compilation (
+               <gbs-build-root>/home/abuild/rpmbuild/BUILD/glib2-2.44.1/gio/.libs
+               <gbs-build-root>/home/abuild/rpmbuild/BUILD/glib2-2.44.1/glib/.libs

+               ) into a /safe/place
+       you may also use generated rpm package glib2-coverage-objects.
+3. install coverage package (glib2-coverage) on the target
+4. run test programs adding LD_LIBRARY_PATH=/usr/lib/dbus-tests/coverage-libs
+       Data gathering is cumulative, so you can run multiple programs one after another.
+       Use GCOV_PREFIX and GCOV_PREFIX_STRIP environment variables to set output directory.
+       If not set, data files (*.gcda) will be generated in /home/abuild/rpmbuild/BUILD/glib2-2.44.1/.
+5. download generated gcda files from the target to /safe/place
+6. put source code *.c files together with object files into a /safe/place
+7. run gcov /safe/place/*.o
+       or gcov -r /safe/place/*.o for only local source code output
