+ * Buildscr for official builds - both source archives and prebuilt
+ * binaries - in the course of overwriting this file as described
+ * above. But we put it here under ifdef, so that it can also be
+ * passed in on the command line for Unix local development builds,
+ * which I treat specially because Unix developers - e.g. me - are
+ * quite likely to run 'make install' straight out of their dev
+ * directory so as to use the bleeding-edge code for day-to-day
+ * running.
+ *
+ * Windows doesn't really need the same treatment, because the easiest
+ * way to install a build properly on Windows is to run the installer,
+ * and the easiest way to do that is to run Buildscr, which will
+ * populate this field its own way. It's only the Unix automake build
+ * where you might go straight from local 'make' to 'make install'
+ * without going through Buildscr.
