# In theory, this plugin supports either aspell or ispell. However,
# virtual/spell has been removed by seemant in favour of just using
# app-text/aspell:
# 20:06 <@seemant> ciaranm: I think I might have removed it, come to
#   think of it, because I was on a kick to get everything converted
#   to aspell instead of ispell
# 20:06 <@seemant> for the simple reason that ispell blows dogs
# So we'll just force people to use aspell...
