I'm using CentOS 7 for development of software that is sometimes used on 
Red Hat Enterprise Linux 7. I conjunction with an update of one of the 
applications, I asked some Red Hat users to install the Qt 4 Assistant 
application via the qt-assistant package (which is used by a "help" 
function in our software.) It seemed like there was no such package in 
the Red Hat package set, however, and I also see no mention of it in 
"package manifests" like 
Yet I can install the package from the "base" repository on my CentOS 

Questions: Isn't CentOS base supposed to contain exactly the same 
packages as Red Hat Enterprise, except in some special cases that relate 
to distribution information, installation sources etc.? Does anyone know 
what's going on with the specific package I mention above?
