Automatic virtual provides for RPM macros?

[Miro Hrončok]

Hello,

today at Nest, somebody said "unfortunately, there is no way to tell what 
package to install to get a particular RPM macro".

I think that having an RPM provides generator for "rpm-macro(__python3)" or 
similar should be a fairly simple exercise.

Would you folks consider that useful?

I think that would be very helpful!


Cheers,

Dan

Would be useful, I have often found myself greping the macros to work out
which file and package a macro is in.

The follow up is to auto-generate the BuildRequires. Probably no mechanism
exists.
