In principle one could also write nroff macros (especially if you have groff available) to process text that's been converted from docbook very minimally, e.g. with a SAX parser or (if the XML was packaged already and known to be well-formed) even sed. > The xsltproc processor, with dependencies, is as > large as a whole POSIX/Unix environment for Windows, sans X11 of > course. This feels wrong. That does seem a bit odd, depending on what's included in the POSIX/Unix distribution -- V6 Unix was pretty small too :-) (but not entirely POSIX compliant), and one doesn't need to distribute a C compiler for basic POSIX conformance. Here, I get (with sizes in bytes): $ urpmq --requires-recursive xsltproc | while read p; do echo -n "$p "; rpm -q --queryformat '%{SIZE}\n' $p; done | awk '{print; t += $2} END { print t}' bash 3136683 dash-static 112538 glibc 24862226 lib64gcrypt11 575228 lib64gpg-error0 14288 lib64pth20 98152 lib64termcap2 14536 lib64uClibc0.9.30.3 576368 lib64xml2_2 1393152 lib64xslt1 380539 lib64zlib1 282188 libgpg-error-common 150451 multiarch-utils 12031 perl-File-Sync 13607 perl-MDK-Common 124467 perl-base 3052855 uClibc 65690 xsltproc 25956 34890955 So libxml itself is 1.3 megabytes -- and checking the two files included, that seems correct -- but xsltproc brings in a total (including itself) of about 33 MBytes via dependencies. Most Linux distributions are likely to have bash and glibc already; a Posix environment could for sure have a smaller shell and libc though. Perl brings in only about 3 MBytes, less than I expected. Did I miss something?
