+This test verifies:
+    1)  that we don't build files when we use the -n, --no-exec,
+        --just-print, --dry-run, and --recon options;
+    2)  that we don't remove built files when -n is used in
+        conjunction with -c;
+    3)  that files installed by the Install() method don't get
+        installed when -n is used;
+    4)  that source files don't get duplicated in a VariantDir
+        when -n is used.
+    5)  that Configure calls don't build any files. If a file
+        needs to be built (i.e. is not up-to-date), a ConfigureError
+        is raised.
