Yes indeed, this would be best in many cases. Some can't really be done
like that, though - like the snippets for Tcl and Python to define the
version, directories for certain types of file and so on. They're
just...informational. Defining them as macros seems the optimal
solution.

This is definitely possible; Mandriva (I know I talk about MDV a lot,
I'm sorry, it's what I know! :>) does this, via an implementation called
'file triggers'. This is not yet upstream, though.

In @rpm5.org, yes.
