[Tutor] Log analyzer

[Mike Yuen]

I'm trying to make a little log analyzer for myself and the problem is, I
want to split each line which initially looks like:

FWIN,2001/09/14,01:44:53 -6:00GMT,24.68.251.251:137,24.53.33.12:137,UDP

I used the split function and got:
'FWIN,2001/09/14,01:44:53', '-6:00', 'GMT,<bunch of numbers here>'

I want each sections boundries to be BETWEEN the commas.  So, for example:
FWIN is one section
2001/09/14 is another
01:44:53 -6:00GMT is yet another.

* Note: each sections size will vary in size.

I know I can take a another pass over the line but i've got literally
1000's of lines to process and taking 2 passes over each line really slows
things done.  So, is  there an efficient way to split the lines?
