Why should we expose the SpellCheck interface in Enchant

I have read much code about enchant and want to implement hyphenation using enchant
but I have one question  in the FL_DocLayout.cpp where spellcheck used.  I think the SpeellManager is enough to deal with our problem, Why should we expose the SpellCheck interface in Enchant. that is not safe


one more question, if we use enchant for abstraction of dictionaries. but most dictionaries have different format. how to  analysis the different format of dictionary
I think the analysis of  dictionary is done by the library the dictionay provide, the  enchant is just Responsible for call it

some different idea?
