+Usage:
+ aerc-mail-setup add Add or update a Gmail, Yahoo, or Outlook account
+ aerc-mail-setup remove Remove generated aerc/isync blocks for an account
+ aerc-mail-setup list List generated accounts
+ aerc-mail-setup sync Run mbsync and notmuch indexing
+
+Secrets are stored through pass(1). Generated private config is written under
+~/.config/isyncrc, ~/.config/aerc/accounts.conf, and ~/.config/notmuch/default/config.
+Removing an account only removes generated config blocks; it does not delete mail or passwords.
