-A small tool to do the statistics legwork on benchmarks etc.
-
-Prepare your data into two files, one number per line
-run 
-	./ministat data_before data_after
-
-and see what it says.
-
-You need at least three data points in each data set, but the more
-you have the better your result generally gets.
-
-Here are two typical outputs:
-

-Here nothing can be concluded from the numbers.  It _may_ be possible to
-prove something if many more measurements are made, but with only five
-measurements, nothing is proven.
