#The context in which the rendering is happening.
#Apart from very useful information you can already get from it:

from nevow.inevow import IRequest
from nevow import rend

class Rendering(rend.Fragment):
  def  render_try(self,context,data):
#you can pass your own to it

from nevow import compy
class IContent(compy.Interface):

class Another(rend.Fragment):
  def  render_try(self,context,data):
     content="this is something I want all the methods in this rendering
process to get known about"

# all the rendering methods called after that can retrieve the 'content'
from context with IContent(context)

Probably there are more useful things context is supposed to be used for
