[Serusers] How to read SERuser list archives offline?

[Ladislav Andel]

Hi,
if I download serusers archives what is the most comfortable way of 
reading it and
searching for information OFFLINE?
If I search through as a plain text it is not very readable.
Do you know any good tool which makes it as a tree of subjects again as 
can be seen in weblist of SER topics?

Thanks for any hints.

Ladislav
