# Emacs 23 daemon capability is a killing feature.

# One emacs process handles all your frames whether
|
|
# you use a frame opened in a terminal via a ssh connection or X frames
|
|
# opened on the same host.
|
|
|
|
# Benefits are multiple
|
|
# - You don't have the cost of starting Emacs all the time anymore
|
|
# - Opening a file is as fast as Emacs does not have anything else to do.
|
|
# - You can share opened buffered across opened frames.
|
|
# - Configuration changes made at runtime are applied to all frames.
