-The IfaceFlavour type is used mainly in an imported Name's Provenance
-to say whether the name comes from a regular .hi file, or whether it comes
-from a hand-written .hi-boot file.  This is important, because it has to be 
-propagated.  Suppose
-
-	C.hs imports B
-	B.hs imports A
-	A.hs imports C {-# SOURCE -#} ( f )
-
-Then in A.hi we may mention C.f, in an inlining.  When compiling B we *must not* 
-read C.f's details from C.hi, even if the latter happens to exist from an earlier
-compilation run.  So we use the name "C!f" in A.hi, and when looking for an interface
-file with details of C!f we look in C.hi-boot.  The "!" stuff is recorded in the
-IfaceFlavour in the Module of C.f in A. 
-
-Not particularly beautiful, but it works.
