What I tried, putting at the end of a file:
Local IspellDict: deAs local variable:
speck-dictionary: de
However, neither is interpreted. When I open the file in question, speck-mode
always uses en as dictionary. The spell checker used is hunspell.
What should I add to a file to change the dictionary of speck-mode?
By the way, I use speck-mode because flyspell-mode is very slow on my
system.
