Wiki-fying docs

["Justin C. Sherrill" <justin@xxxxxxxxxxxxxxxxxx>]

I've noticed that there's been a number of people who have wanted to
contribute to docs, but the process of installing the doc-proj port and
all its dependencies, plus talking SGML, plus building it, is forming a
sort of barrier to entry.  I think I'm the only poor soul that's done it.

I was thinking we could copy the existing docs into a Wiki, and see how
contributions change from there.  Mashing wiki changes back into CVS may
be less laborious than putting other people through the docproj wringer. 
Can anyone think of any objections?
