+  *
+  * Each testDir can also have a __defaultFlags.flags file, which provides
+  * compiler flags and is used unless there's a specific flags file (e.g. for
+  * test pos/A.scala, if there's a pos/A.flags file those flags are used,
+  * otherwise pos/__defaultFlags.flags are used if the file exists).
