+  <description>
+    0bootstrap creates native binary packages (debs, RPMs, exes, etc) for use on systems
+    where 0install is not already present.
+
+    Unlike 0export, the packages do not contain the programs themselves. They are just
+    launchers that trigger 0install to get the actual program.
