I'm working in Kile on a LaTeX file with *.mng extensions. Due to the strange file extension Kile 
does not recognize it as source LaTeX file and almost all editing capabilities provided by Kile 
are gone. For example it does not recognize document structure and the autocompletion of 
references and citations is gone. How can I make Kile aware that this is in fact a LaTeX file?
