Vord frequency histogram as an indicator of the text category

[-JKP-]

In the old days, when I still had a Unix machine on my desk, I found that one could do almost anything one wanted with a small set of Unix commands. "grep" was most helpful of all.
For the more complicated stuff, basic 'awk' and if necessary 'perl' scripts did the job.

Since a Mac is Unix under the hood (BSD Unix) and I have a Mac... I still find those very useful tools and Perl is still a very viable and useful Web tool (and very good for parsing text).
