+  In the first stage, only files in `SRCDIR` which match `FINDDATARULES` (see below) will be built, with files in `DATADIR` serving as includes.
+  In the second stage, the remaining files in `SRCDIR` will be built, with the files built during the first stage, in addition to any files in `INCLUDEDIR`, serving as includes.
