+=head1 CACHING
+
+  Because the virtual systems are installed with the debootstrap
+ tool there can be a lot of network overhead.
+
+  To minimize this the .deb files which are downloaded into the
+ new instance are cached upon the host in the directory
+ /var/cache/apt/archives. 
+
+  When a new image is created these packages are copied into the new
+ image - before the debootstrap process runs.  This will avoid a
+ the expensive fetch from the network.
+
+  If you wish to clean the cache run on the host:
+
+  apt-get clean
