scdoc listed as optional dependency but make install results in a build error:
go: downloading golang.org/x/net v0.1.0
./hut completion bash >hut.bash
./hut completion zsh >hut.zsh
./hut completion fish >hut.fish
scdoc <doc/hut.1.scd >doc/hut.1
/bin/sh: scdoc: command not found
make: *** [doc/hut.1] Error 127
This sounds tricky to fix without introducing a lot of complexity in the Makefile.
Done
