;;; ssh.el --- When working remotely -*- lexical-binding: t -*-

;; Sets the value of the TERM variable to "dumb" when logging into the remote
;; host. This allows me to check for the value of "dumb" in my shell's init file
;; and control the startup accordingly. You can see in the (shamefully large)
;; commit, 0b4ef0e, that I added a check like this to my ~/.zshrc. I've since
;; switched from z-shell to fish. I don't currently have this check in
;; config.fish, but I may need to add it one day soon.
(setq tramp-terminal-type "dumb")
;; Maximizes the tramp debugging noisiness while I'm still learning about tramp.
