I'm using CentOS 7 for development of software that is sometimes used on

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
machine.
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?

The qt-assistant package is available in RHEL-7:
$ sudo yum list qt-assistant
qt-assistant.x86_64 1:4.8.7-2.el7 rhel-7-server-optional-rpms
Right. I notice the word "optional" here - I guess this is where some of
the confusion comes from, as the Red Hat doc mentioned above does not
say anything about optional packages, it just mentions base and
"supplementary" channels. Evidently, optional rpms are not enabled on
the system mentioned earlier...
Also, this must mean that CentOS "base" is not the same as Red Hat
"base". Right?
