+In the past prior to Fedora 24, libstatgrab had only 1 package for 2 programs
+with different usage, while putting them inside one package seems reasonable,
+however in order to reduce the size of the package, we decided to halve the
+original package, now users can choose which to install, saidar or statgrab.
