Calling tool-bar-mode, menu-bar-mode or scroll-bar-mode from
early-init.el seems to cause a 15-30% slowdown in startup time, possibly
for loading the UI libraries early.
Also, loading early-init.el eagerly from init.el causes a GC hit for
Emacs 25/26 users. It's too early to use this optimization.
This commit adds bin/doom, which acts as the middle man that make once
was (and will stay for a while, though the documentation will shift away
from using it). It does everything the previous make interface did, but
is faster and more flexible. bin/doom should eventually replace the
makefile.
bin/doom also makes it easier to run Doom outside of ~/.emacs.d and
~/.doom.d with, for example:
bin/doom run -p ~/.other.doom.d/ -e ~/.other.emacs.d
bin/doom.cmd is included for Windows users, but I don't recommend using
it yet. It hasn't been tested nor have I ever written a batch script
before.
Also update init.example.el with new defaults.
