As I was not able to reach author of Pod::DocBook v1.2 (UNAUTHORIZED RELEASE) Nandu Shah, I ressurected it from CPAN and created Pod::2::DocBook. This version futures many handy options that can be used to produce parts of docbook document, like sections, articles etc.
I use it my MakeFile this way:
pod2docbook --title='example module POD' --no-header --doctype=section $ $@
and then I xinclude it to the docbook document.
Hopefully others will also take advantage of this module.
