@tomjennings I'm the original author of pygopherd, so I use it. It supports a number of different annotation formats. I use UMN-style .cap, .Links, etc. Mainly because nothing else existed when I set it up, but also because I host mirrors of sites that ran UMN-style. pygopherd also supports gophermap. See the manual at https://github.com/michael-lazar/pygopherd/blob/master/doc/pygopherd.pdf . Section 5.9 documents UMN-style links, and there are links to the gophermap spec as well.
