Use BoostBook standalone?

Good evening list,

my project (.c and .h, basically no c++) requires documentation in 
DocBook. In the past, I have been a contented user of doxygen. BoostBook 
has the capacity to generate DocBook .sgml from doxygen-annotated code, 
is that correct?

My question: can I use BoostBook to generate DocBook .sgml from my 
doxygen-annotated header files without using Boost itself? If so, how? I 
have been trying to find my way in the Boost distro, but I didn't yet 
fathom its intricacies.

Thanks,
