Now we could explicitly state we also save patches. E.g. changing the
above bullet to:
* The original source code for all packages; this has been saved in...
^^^^^^^^
And adding:
* The patches applied to the source code before building it, along with
a file named 'series' that lists the same patches in the order they
have been applied.
But this can be done in a later commit, so:
