Now on speller.
Configuration objects we need more care as they could be in
a speller. Does aspell figure out what is going on for us?
It is added, except for the case that we get it from the speller.
$<- and [<-
$<- done.
$ accessor for AspellConfig is very slow.
Profile it.
Module info.
In place, but needs testing. Crashing at times.
dict_dirs is causing the problem. So that one element is now
turned off.
Filters, documents, etc.
Documents okay. Filters - just set them in the
config$add-filter technique.
In the future, could write our own filter in R!
Think how to get the setSpellConfig() and $<-, etc. to add
to a list
