### What do the platform tags in manifest.xml mean and when are they added?

I can't seem to find the answer to this in the manifest xml reference, but in some manifest files I see tags like:

  <platform os="ubuntu" version="9.04"/>
<platform os="ubuntu" version="9.10"/>
<platform os="ubuntu" version="10.04"/>


What do they represent and when are these tags added?
