Using variables in src\site\apt\index.apt - is there a default-index.apt or even inheritance?

[torsten . reinhard]

Hi, 
 
what´s the magic behind the default Site generation ? Without specifying 
anything the index.html is being generated containing
 
About ${project.name}
${project.description}
 
The index.html looks like:

...
<div id="bodyColumn">
      <div id="contentBox">
        <div class="section"><h2>About Proficio API</h2><p>Proficio sample 
application from &quot;Better Builds with Maven&quot;</p></div>
      </div>
    </div>
...

When I now create my own src\site\apt\index.apt File, the Default with 
"About...." and "Description" is gone.

a) is there a default-index.apt file I can "copy and modify"? A 
default-site.xml I´ve found in the maven-site-plugin-<version>.jar
b) how can I use "dynamic content" in an apt File,e.g. ${project.version} 
or what´s the recommended way ?
 
I´ve read something at 
http://www.nabble.com/-M2--Insert-variables-in-xdoc-apt-files-to5366829.html#a5371135
Is that the recommended way to play around with the directories using the 
filtering process?

Thanx for any hints, 

Torsten
