Somehow the design of Squeak omits "fileIn" from the same menu as "fileOut" so it's hard to know what works on fileOut is going to work on fileIn.  I'm trying to convert software written in another Smalltalk and it would help to file it in.  At least adopting each class to Squeak's fileIn format would be easier than copying in every method one at a time.  So please help me fileIn.  Thanks.
