XML format

[jbasko]

Something generic where you can just specify the root element's xpath and then have this:

<config>
<uploads>
  <threads>1</threads>
  <enabled>true</enabled>
  <db>
    <user>root</user>
    <password>secret</password>
  </db>
</uploads>
</config>

XML could also easily support meta information through attributes:

<enabled type="boolean">true</enabled>
<password required="true" />
