As usual with free software projects, licenses are incompatible: * groff: GPLv3 (viral, clearly the worst one) * Heirloom Doctools: CDDL (viral, but a different virus) * Solaris 10 roff: CDDL * Plan 9 roff: Lucent Public License (GPL-inxompatible) * Documenters Workbench: Eclipse Public License (viral, yet another virus) * neatroff: ISC So neatroff is the only one that is fully free, and it was specifically started as a fresh implementation to avoid the implementation baggage that comes with all the historical implementations. The reason i'm sticking to groff is that groff has been the typesetter predominantly used by BSD systems during the last 25 years, that it is still dominant as a manual page formatter, which implies maintaining compatibility with groff is crucial while compatibility with anything else is nice to have at best, that it is good enough for my (moderate) typesetting needs, and that even though its developer base is quite limited, it still has the largest number of active developers. I think it's a general phenomenon that you can't have full unification among Free Software projects. The best you can usually get is some cooperation to improve compatibility. Yours, Ingo
