Dynamic version & release numbers

[Erez Zilber <erezz voltaire com>]

Hi,

How can I set the version & release number dynamically in a spec file? 
Currently, I do that in the following way:

%define version 3
%define release 456

Version : %{version}
Release : %{release}

I'd like to do something like:

version = grep a value from some file
release = grep a value from some file

Version : %{version}
Release : %{release}

Thanks in advance
