[ESS] could intending around code chunks be fixed in Sweave docs?

[Vitalie Spinu]

Thanks Kasper, your description is correct. Polymode is general

Full documentation of the ess-developer is here:

  http://ess.r-project.org/Manual/ess.html#ESS-developer

There is not much to add to it except that knowledge of how namespaces
work might be handy.
