+# Dir scanner finds it and adds it to the dir's entries.
+# Unfortunately FS.py's File.exists() method checks it later and finds
+# it looks like a stale build copy of a missing source, so it deletes
+# it.  And then it's later discovered to be missing since it's still
+# in the dir's entries list.  The fix for this is to test for missing
+# source files in the dir scanner (Scanner/Dir.py), and delete them
+# (just like File.exists() does if they're found in the build dir
+# rather than making entries for them.
