Making Programs Faster

Sample Program: Mail Folder Analyzer

I wanted a sample program written by someone else
This one was kindly provided by Mr. Robert Spier
- He used it in last year's optimization tutorial
It's in mfa1-n.pl
The program analyzes an mbox-format file

        perl mfa1.pl MBOX

The output might look like this:
