The shell to use comes from the first non-nil variable found from these:
explicit-shell-file-name in Emacs, ESHELL in the environment or SHELL in the
environment. If none is found, /bin/sh is used.
If a file ~/.emacs_SHELLNAME exists, it is given as initial input, simulating
a start-up file for the shell like .profile or .cshrc. Note that this may
lose due to a timing error if the shell discards input when it starts up.
The buffer is put in shell-mode, giving commands for sending input
and controlling the subjobs of the shell.
The shell file name, sans directories, is used to make a symbol name
such as `explicit-csh-arguments'. If that symbol is a variable,
its value is used as a list of arguments when invoking the shell.
Otherwise, one argument `-i' is passed to the shell.

;;; Directory tracking
;;; ===========================================================================
;;; This code provides the shell mode input sentinel
;;; SHELL-DIRECTORY-TRACKER
;;; that tracks cd, pushd, and popd commands issued to the shell, and
;;; changes the current directory of the shell buffer accordingly.
;;;
;;; This is basically a fragile hack, although it's more accurate than
;;; the original version in shell.el. It has the following failings:
;;; 1. It doesn't know about the cdpath shell variable.
;;; 2. It only spots the first command in a command sequence. E.g., it will
;;; miss the cd in "ls; cd foo"
;;; 3. More generally, any complex command (like ";" sequencing) is going to
;;; throw it. Otherwise, you'd have to build an entire shell interpreter in
;;; emacs lisp. Failing that, there's no way to catch shell commands where
;;; cd's are buried inside conditional expressions, aliases, and so forth.
;;;
;;; The whole approach is a crock. Shell aliases mess it up. File sourcing
;;; messes it up. You run other processes under the shell; these each have
;;; separate working directories, and some have commands for manipulating
;;; their w.d.'s (e.g., the lcd command in ftp). Some of these programs have
;;; commands that do *not* effect the current w.d. at all, but look like they
;;; do (e.g., the cd command in ftp). In shells that allow you job
;;; control, you can switch between jobs, all having different w.d.'s. So
;;; simply saying %3 can shift your w.d..
;;;
;;; The solution is to relax, not stress out about it, and settle for
;;; a hack that works pretty well in typical circumstances. Remember
;;; that a half-assed solution is more in keeping with the spirit of Unix,
;;; anyway. Blech.
;;;
;;; One good hack not implemented here for users of programmable shells
;;; is to program up the shell w.d. manipulation commands to output
;;; a coded command sequence to the tty. Something like
;;; ESC | <cwd> |
;;; where <cwd> is the new current working directory. Then trash the
;;; directory tracking machinery currently used in this package, and
;;; replace it with a process filter that watches for and strips out
;;; these messages.
;;; REGEXP is a regular expression. STR is a string. START is a fixnum.
;;; Returns T if REGEXP matches STR where the match is anchored to start
;;; at position START in STR. Sort of like LOOKING-AT for strings.

"Tracks cd, pushd and popd commands issued to the shell.
This function is called on each input passed to the shell.
It watches for cd, pushd and popd commands and sets the buffer's
default directory to track these commands.
You may toggle this tracking on and off with M-x dirtrack-toggle.
If emacs gets confused, you can resync with the shell with M-x dirs.
See variables shell-cd-regexp, shell-pushd-regexp, and shell-popd-regexp.
Environment variables are expanded, see function substitute-in-file-name."
