> I won't say more on this topic. We are on a groff list. Considering that groff's own documentation is (perversely? ironically? choose your own adverb) written in Texinfo format, a discussion of the merits of that format could be considered on topic here (if a bit academic, since no one is champing at the bit to port groff's manual to any other format).
I'm personally indebted to whoever on this list first pointed out that you can pipe info(1) through less(1) and view the entire groff manual as one long page. This has been a godsend and is the only way I've accessed the groff manual over the past 5+ years. I hacked together a sed script that further pares it down by, among other things, removing all the macro-package-specific stuff (the only macro packages documented in info format are ones I don't use, but which gave me false positives when using less's search) and the various indexes (redundant in this format but making up about a third of the line count). In case it's useful to anyone else: alias infogroff="info groff | sed -E '/^[0-9] Macro Packages/,\ /Prev: Macro Packages, *Up: Top$/\ {/Prev: Macro Packages, *Up: Top$/!d}; /^[0-9.]+ .gtroff. Output/,\ /Prev: gtroff Output, *Up: File formats$/\ {/Prev: gtroff Output, *Up: File formats$/!d}; /^Appendix A Copying This Manual$/,\$d; s/^File: [^,]+, +(Node: [^,]+),.+/\1/' | less" No idea whether this works with a non-GNU sed, or any shell besides bash.
