+%description
+The purpose of the %{name} tool is to provide an automated way of converting
+the installed other-than-RHEL OS distribution to Red Hat Enterprise Linux
+(RHEL). The conversion is done in situ without the need to restart the system.
+The tool replaces all the original OS-signed packages with the RHEL ones.
+Available are conversions of CentOS 5/6/7 and Oracle Linux 5/6/7 to the
+respective major version of RHEL. The original OS always converts to the latest
+RHEL minor version.
