Remove the dependency on the ancient and unmaintained texi2html, which was difficult to get running on most distros other than openSUSE. There are two more modern alternative approaches which can replace this: - Use texi2any - Use makeinfo --html --no-split The latter seems to be the standard way these days, so we switch to that; however we keep Makefile rules for all three, and a phony meta-rule 'manual-single-html-all' to allow quick comparison between them. Make tweaks accordingly to minimise the differences and improve the output. The rules for the older two approaches do not get triggered by default. Fixes #21: https://github.com/aspiers/stow/issues/21
