Use zgen or antigen. Here is how to do it with zgen:
zgen load zsh-users/zaw zgen load willghatch/zsh-zaw-todoman
Be sure to load zaw before this plugin, or it will scream at you.
What is this?
A very basic zaw source for the todoman task management program.
It only has one action for now -- marking a task as done.
Also, it doesn't play very well with todoman's colored output. It is rough to the point that I'm really only publishing it as an example to list in the not-in-the-main-zaw-repo source list.
BSD-3 (same as zaw)
