I'd like to suggest (in the interest to keep 'mupdf.tcz' as small as possible) to not include the extra tools (i.e. 'xpsdraw', 'pdfclean', 'pdfinfo', 'pdfextract', 'pdfdraw', and 'pdfshow') in this extension.
Otherwise the size of the extension roughly doubles compared to the current version in the repository. I could imagine that those tools could become an extension in their own right (e.g. 'mupdf-extras.tcz'). In my (albeit limited) testing none of them were required by the main executable.
