Please let PDF die, like Flash. :) I hate that R's documentation and vignettes, before downloading a package, are almost entirely rendered in PDFs.> Ok, looking at the features of Sphinx more closely now.. Since there are various people here knowledgeable about Sphinx.> More questions..> Does Sphinx support output to docbook?Not natively, but it should be possible to write a converter: https://github.com/HolgerPeters/sphinxcontrib-docbookI think the basic process is to run sphinx with the XML builder and then transform that XML to docbook XML.My question would be: why do this?Is this for PDF support?It looks like there is a builder that can be used to produce PDF output: https://github.com/brechtm/rinohtypeHowever, it requires Python3.3+How important is PDF support? Just curious as I typically only use HTML for documentation.
