+## This script pulls all my git repos that I use in my config. It will only pull
+## them if they don't exist. Rather than use the import approach suggested in
+## the chezmoi howto, this doesn't require me to keep 'syncing' changes when I
+## work in these repos directly. The tradeoff is that it will only pull the
+## latest master, which is totally fine with me.
