Hello Lex, Thank you very much for yet another quick response!
You're right about me judging erroneously what *a2x* is --- and isn't. With hindsight, I would have said, instead: "It seems this is a quite common---and, not strangely, old---problem relating to some users' misconceptions about *a2x*." I have now dutifully installed *xsltproc*, the *DocBook XSL Stylesheets*, *dblatex*, and *w3m*, per https://asciidoc.org/a2x.1.html#X1, as you seem to have suggested. This, however, can only take me so far, i.e., beyond *xmllint* and the relevant *XML* *DTD*s. What follows is the output I'm now getting, beyond the usual first 18 lines of code: *a2x: executing: "dblatex" -t pdf -p "/usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.xsl" -s "/usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.sty" -V "/home/zam/Downloads/asciidoc-9.0.5/doc/article.xml"Build the book set list...xsltproc -o doclist.txt --xinclude --xincludestyle doclist.xsl /home/zam/Downloads/asciidoc-9.0.5/doc/article.xmlBuild the listings...xsltproc -o listings.xml --xinclude --xincludestyle --param current.dir '/home/zam/Downloads/asciidoc-9.0.5/doc' /usr/share/dblatex/xsl/common/mklistings.xsl /home/zam/Downloads/asciidoc-9.0.5/doc/article.xmlxsltproc -o article.rtex --xinclude --xincludestyle --param current.dir '/home/zam/Downloads/asciidoc-9.0.5/doc' --param listings.xml '/tmp/tmpYrmfo_/listings.xml' /tmp/tmpYrmfo_/custom.xsl /home/zam/Downloads/asciidoc-9.0.5/doc/article.xmlXSLT stylesheets DocBook - LaTeX 2e (0.3.10)===================================================Image 'dblatex' not foundImage 'images/smallnew.png' not foundImage 'images/tiger.png' not foundBuild article.pdfbuilt-in module pdftex registeredno support found for ifthenno support found for ifxetexno support found for fontspecno support found for xltxtrano support found for fontencno support found for inputencno support found for fancyboxbuilt-in module makeidx registeredno support found for asciidoc-dblatexbuilt-in module bibtopic registeredbuilding additional files...checking if compiling is necessary...the output file doesn't existpdflatex -interaction=batchmode article.texpdflatex failed/usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.sty: File `docbook.sty' not found./usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.sty:8: Emergency stop./usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.sty:8: leading text: ^^MUnexpected error occuredError: pdflatex compilation faileda2x: ERROR: "dblatex" -t pdf -p "/usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.xsl" -s "/usr/local/etc/asciidoc/dblatex/asciidoc-dblatex.sty" -V "/home/zam/Downloads/asciidoc-9.0.5/doc/article.xml" returned non-zero exit status 1* It seems my main problem now is *pdflatex* cannot find the *docbook.sty *file in question. If that's right, could you please point me to the place where I can get it? It would be nice, too, if you could explain to me what's with all the *Image [...] not found *and the *no support found for... *messages, since (1) such images *do* exist in the *asciidoc-9.0.5/images *directory, and (2) I have TexLive's latest version installed and have thus far used it successfully. Sorry for the rather general amateurish character of my inquiry. Please, feel free to answer my questions whenever you have the time to do so.
