[$] A look at the aerc mail client

Email has become somewhat unfashionable as a collaboration tool for
open-source projects, but there are still a number of projects—such as
PostgreSQL and the Linux kernel—that expect contributors to send and
review patches via email. The aerc
mail client is aimed at developers looking for a text-based, efficient, and
extensible client that is meant to be used for working with Git and
email. It uses Vim-style keybindings by default, and has an interface
inspired by tmux that
lets users manage multiple accounts, mails, and embedded terminals at once.
