+Finally, reset the epoch used for the $(Days) value computed in
+Buildscr for the Windows binary version resource. It's probably not a
+good idea to set it to _today_ (since it might clash with the
+zero-valued field used in actual releases), so perhaps we should start
+it 1000 days before the release date so as to have a largish number
+recognisable as being the right kind of thing by its order of
+magnitude. So, do this:
+
+ perl -e 'printf "%d\n", time/86400 - 1000'
+
+and then substitute the resulting value into the definition of 'Epoch'
+in Buildscr.
