There are a couple problems with this test. First, DiskDoubler, one of the
hotest sellers at Boston MacWorld wasn't tested. Secondly, there are no
timings... this might be a key issue... so, I'll just whip up the test I
did myself.

Files used: Zterm package:
Application = 144K
Doc (write) = 54K
Doc (write) = 4K
Zterm doc = 1K
Text doc = 4K
Text doc = 3K
Text doc = 3K
Total = 213K

I hope this makes sense. The two uncompression tests are time tests, while
the compression test is both time and size. This test is far from complete.
I want to test Diamond, and test more files, sound files, graphic files.
I also want to do a report on the ups and downs of the feature selection,
user interface, and price, all of which are important as the numbers.
