Even though it's just a new informational link, I'm guessing we still need
to file an FPC ticket for that?


I think that macros we care about should be on that page, not just at that
link.  However, you should check with tibbs/FPC about whether the
definitions/list of macros are an altogether dated concept.   When I was
there we used those because spec files are just shell scripts.  For a
sysadmin to become a packager, they just needed to understand a few
concepts about the structure of the spec file but otherwise they just put
their steps from the command line into the spec.

Defining the macros on the page allowed those users to see how the macro
replaced some steps of their manual procedure.

However, that may no longer be the audience of the guidelines.  It may be
that they're now targeting programmers or packagers who don't have the same
intimate relationship to the command line as sysadmin and have a greater
comfort learning a domain specific language to do a job.

In that case, perhaps the entire concept of enumerating the macros is
unneeded for that target audience.  Instead, simply introducing the macros
when they're used in the guidelines is enough.  Talk to tibbs/FPC about
what their thoughts are.

Rather than emphasising the absence of setup.py, I'd emphasise the use of
wheel files:

* "Defining an RPM based on a wheel build process"
* "Defining an RPM based on a setup.py file"


I would not emphasize the use of wheel files as they are not source and
from flit's documentation, it doesn't appear that wheels are even central
to it (contrast how much wheel is mentioned in  its documentation compared
to pyproject.tom).  Instead I would emphasize flit itself as the build tool
which we're using to transform the source into the files on our systems.
If there's ever an alternative to flit which builds with wheels as part of
that process we'll need new guidelines based on that so using wheel as the
prime keyword that people associate with this build process instead of flit
is not future proof either.
