  Nifty!  Two questions:

1. Why isn't this mentioned in the BSD man page awk(1), or in the
   /usr/doc documentation about awk?
2. What happens if you actually want to read in a file that has = in
   the filename?  How am I supposed to know what happens if the
   feature isn't mentioned in documentation? :-)
