What macros do you use? I have some simple programs that generate documents to print out, and I use LaTeX and a bunch of packages. It takes hundreds of megabytes of software with all the packages. I've long toyed with using the MOM macros but can't get motivated to rewrite my programs and learn troff.
It used to bother me that groff doesn't support Unicode (as far as I can tell) but then realized that all I write is English so why am I fetishizing Unicode? groff will get me any accented character that I would realistically need.
