dnl AS_DOCBOOK([, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]])
dnl checks if xsltproc can build docbook documentation
dnl (which is possible if the catalog is set up properly
dnl I also tried checking for a specific version and type of docbook
dnl but xsltproc seemed to happily run anyway, so we can't check for that
dnl and version
dnl this macro takes inspiration from
