Re: [Paparazzi-devel] Paparazzi on Linux and Lisa design questions

[antoine drouin]

a simpler bloc diagram :
  http://paparazzi.enac.fr/wiki_images/Lisa_l_bloc_diag_simple.png

I have started to split the doc for Lisa between a developer part and
a user part, but it's still mostly empty for now.
I think we should do the same for the rest of the wiki : users don't
want to be overwhelmed with too technical informations, and developers
don't want to lose time with a bunch of details that may look trivial
to them.

Now how do we get the search function of the wiki to handle that
user/developer separation ? tags ? using two wikis ?
What you guys think ?
