GDP: regrouping and plan

[Graham Percival]

I've updated GDP stuff at:

http://opihi.cs.uvic.ca/~gperciva/

There you can find rewritten/expanded instructions for GDP Formatters 
and Rewriters (formally known as "trivial/easy/" and "medium" -- I 
always felt bad about typing "trivial") and the most recent version of 
the docs.


Helpers: please download your source file (if you're not using git), 
make one or two small changes, then send me the result.  If you already 
did this, please do so again.  :)

In case you're wondering why I'm so obsessed about this, in the past I 
_have_ had to reject hours of documentation work that other people had 
done, which causes bad feelings in everybody.


Timeframe: next Wed evening (pacific time), I'll finalize instructions 
and "freeze" the doc sources.  Then you guys edit away, and send me 
whatever you have before next Tues.  I'll put everything together again, 
 build new output, and then we start again.  If you're not using git, 
then I need to know what version of the file you start editing.  So make 
sure you get your file from opihi.

Cheers,
- Graham
