[Tdg] presentation

[Graham Wakefield]

I'\ve just been going through it, and two things occur to me so far.

1. I'd like to change the title of 'Survey of Existing Tools' to  
'Comparison of Existing Tools', since we didn't actually do a survey  
in the traditional sense.

2. On that slide, please anyone pipe in to make any comments that  
they wish to about specific tools and how the scale or do not scale  
etc... cos there are a few things on there that I've never even heard  
of.
