Please document expressions for depencencies

[cryptomilk]

The Spec file format doesn't describe the expressions implemented e.g. for Requires. There are several operators like and, or, if, unless, else, with and without.

Example:

Requires:       ( pkgA >= 1.2.3 or pkgB )

I suggest looking at the top-level manual for a wider perspective of what's documented. You'll find multiple articles on dependencies there, including one on boolean dependencies: https://rpm-software-management.github.io/rpm/manual/

The way our manual is constructed leaves a lot to be desired for sure, for proper organization it'd call for something other than bunch of files in markdown really. Besides historical reasons, there's a reason why dependencies are described outside spec syntax: these exist in various forms outside the spec, so documenting them as spec syntax would be overly limiting.

Then it should be interlinked. I would expect that a "Spec file format" document either explain everything or link accordingly.

I don't disagree, just pointing out that you'll be missing a lot of documentation if you only look at the spec syntax document currently.
