Micheal;
Any chance of you providing a 'cookbook' on howto do this? Just an
illustration of the commands to execute and what to do in what order?
I think we could all use this, and I for one am planning on doing this
at work in teh near future. While I do not mind learning, I wouldn;t
mind some pointers from someone who has already done it (see my
tagline).
Cheers
Chris
