Multilungual Nimdoc

[Hlaaftana]

I have no idea if this works, but as an idea maybe you could do:
    
    
    proc foo*() =
      when defined(englishDocs):
        ## English docs here
      when defined(chineseDocs):
        ## Chinese docs here
    
    
    Run

then build docs with `nim doc -d:englishDocs foo.nim` for English doc pages, 
and `nim doc -d:chineseDocs foo.nim` for Chinese doc pages.

To make it less strict (i.e. for docs to work in IDE) you could check for 
`defined(englishDocs) or not defined(nimdoc)`.
