 It's not intended to be useful, it was started as a learning exercise. As it became clear it would take a little longer than the couple of hours
 I originally estimated it at, I stopped work on it for the moment, till I have more free time.
 
 ## History 
 
-FSharp.AbsIL was originally a separate research project by Don Syme at MSR Cambridge, as time went by it became clear that F# was the more interesting/important
-research area, so FSharp.AbsIL was rolled into the F# compiler. Now the compiler sources are available under an open source license I have taken advatage of this
