For connecting to an Erlang node using erl -remsh from within Emacs.
Remsh provides a way to use erl -remsh to connect to an already
running Erlang node, from within Emacs, as an inferior Erlang shell.
Use M-x remsh-connect to connect.
Once connected, C-c s will set the remsh-connected inferior Erlang shell
as the buffer to use when compiling Erlang code from within Emacs.
This is compiling and hot-loading code directly from Emacs
into a running node.
If the connection is broken for some reason or the Erlang node is
restarted, C-c r will attempt to reconnect.
Dependencies (available via elpa or melpa):
Use for example M-x package-install <pkg> to install them. Refer to
melpa getting started for
info on how to set up your Emacs to access packages from melpa.
