<para>What this bit of evil does is check out head, stable/7 and
stable/6. We create the empty checkout directories under
<acronym>SVN</acronym>'s control. In <acronym>SVN</acronym>,
subtrees are self identifying, like in <acronym>CVS</acronym>.
We check out head and clone it as stable/7. Except we don't
want the head version so we <quote>switch</quote> it to the
7.x tree location. <acronym>SVN</acronym> downloads diffs to
convert the <quote>head</quote> files to
<quote>stable/7</quote> instead of doing a fresh checkout.
The same goes for stable/6. This does, however, definitely
count as abuse of the working copy client code!</para>
