title: how to build scl, example are old and rpmlint contradict the documentation?
body: <p>I read the <a href="https://www.softwarecollections.org/en/docs/guide/" rel="nofollow noreferrer">official documentation</a>, some <a href="https://github.com/sclorg/scl-examples" rel="nofollow noreferrer">examples on github</a> and <a href="https://www6.atomicorp.com/channels/source/atomic-php52/php52.spec" rel="nofollow noreferrer">on atomicorp</a> . But I am still confused!</p>
  
  <p>Should have to make 2 specs? One to build the tools and another one for a metapackage?</p>
  
  <p>If yes why atomicscorp's spec file seem to be a mix of spec and the meta-spec files ?</p>
  
  <p>Moreover with rpmlint 1.10 on metapackage seem to contracdict the documentation and examples. I have this error:</p>
  
  <pre><code>scl-runtime-package-without-%scl_files
  SCL runtime package must contain %scl_files in %files section.
  </code></pre>
  
  <p>And <a href="https://github.com/sclorg/scl-examples/blob/master/scl-bar24/scl-bar24.spec" rel="nofollow noreferrer">examples</a> used  %scl_files statement into the runtime part (line 172)</p>
  
  <p>Any help is welcome</p>
  
  <p>Thanks</p>
