Facilitate use of multiple local and remote Emacs shell buffers.

+Multishell is available via Emacs package manager, in ELPA. Install "multishell" from the `M-x package-list-packages` listing.
+
+I use the emacs shell a *lot*, including separate shells for separate
+project, and more shells for access to remote systems (which I do a lot, as
+a systems administrator). On top of emacs' powerful shell and tramp
facilities, use a `multishell` (customization-activated) key binding to:
* Get to the input point from wherever you are in a shell buffer,
-* ... or to one of your shell buffers if you're not currently in one.
+ ... or to any of your shell buffers, from anywhere inside emacs.
+
* Use universal arguments to launch and choose among alternate shell buffers,
-* ... and select which is default.
+ ... and change which is the current default.
+
+* Easily restart disconnected shells, or shells from prior sessions
+ ... the latter from Emacs builtin savehist minibuf history persistence
+
* Append a path to a new shell name to launch a shell in that directory,
-* ... and use a path with Emacs tramp syntax to launch a remote shell.
+ ... and use a path with Emacs tramp syntax to launch a remote shell -
+ for example:
- For example:
+ * `#root/sudo:root@localhost:/etc` for a buffer named "#root" with a
+ root shell starting in /etc.
- * `/ssh:example.net:/` for a shell buffer in / on
- example.net; the buffer will be named "*example.net*".
+ * `/ssh:example.net:/` for a shell buffer in / on example.net.
+ The buffer will be named "*example.net*".
* `#ex/ssh:example.net|sudo:root@example.net:/etc` for a root shell
starting in /etc on example.net named "*#ex*".
-(NOTE that there is a frequent problem with specifying a remote homedir
-using tramp syntax, eg `/ssh:example.net:` or `/ssh:example.net:~`. That
-sometimes fails on an obscure bug - particularly for remote+sudo with
-homedir syntax. Until fixed, you may need to start remote+sudo shells with
-an explicit path, then cd ~. With `multishell`s dir-tracking persistent history, you'll be able to use completion to start that shell in the right place, in your subsequent sessions.)
-
-Customize-group `multishell` to select and activate a keybinding and set
-various behaviors. Customize-group `savehist` to preserve buffer
-names/paths across emacs sessions.

-Change Log
-----------
-* 2016-01-16 1.0.5 Ken Manheimer:
- - History now includes paths, when designated
- - Actively track current directory in history entries that have a path.
- Custom control: multishell-history-entry-tracks-current-directory
- - Offer to remove shell's history entry when buffer is killed
- (For now, the only UI way to remove history entries.)
- - Fix - prevent duplicate entries for same name but different paths
- - Fix - recognize and respect tramp path syntax to start in home dir
- - But tramp bug, remote+sudo hops to a home dir can fail, get wedged.
- - Simplify history var name, migrate existing history if any from old name
-* 2016-01-04 Ken Manheimer - Released to ELPA
-* 2016-01-02 Ken Manheimer - working on this in public, but not yet released.
-
- TODO
-----------
-* Isolate tramp sporadic failure to connect to remote+sudo+homedir syntax
- (eg, /ssh:xyz.com|sudo:root@xyz.com: or /ssh:xyz.com|sudo:root@xyz.com:~)
-* Find suitable, internally consistent ways to sort tidy completions, eg:
- - first list completions for active shells, then present but inactive,
- then historical
- - some way for user to toggle between presenting just buffer names vs
- full buffer/path
- - without cutting user off from easy editing of path
-* Find proper method for setting field boundary at beginning of tramp path
- in the minibuffer, in order to see whether the field boundary magically
- enables tramp completion of the path.
-* Assess whether option to delete history entry on kill-buffer is
- sufficient.
+ * 'interior/ssh:gateway.corp.com|ssh:interior.corp.com:' to go via
+ gateway.corp.com to your homedir on interior.corp.com. The buffer
+ will be named "*interior*". You could append a sudo hop, and so on.
+
+* Thanks to tramp, file visits from the shell will seamlessly be in
+ the auspices of the target account, and relative to the current
+ directory, on the host where the shell is running.
+
+See the `multishell-pop-to-shell` docstring (in
+[multishell.el](multishell.el)) for details, and
+[getting-to-a-shell.md](getting-to-a-shell.md) for the nitty-gritty
+decision tree that determines where different hits of the keybinding go.
+
+Customize-group `multishell' to select and activate a keybinding and set
+various behaviors. Customize-group `savehist' to preserve buffer
+names/paths across emacs restarts.
