;;; Commentary:

;; Magit is a text-based Git user interface that puts an unmatched focus
;; on streamlining workflows.  Commands are invoked using short mnemonic
;; key sequences that take the cursor’s position in the highly actionable
;; interface into account to provide context-sensitive behavior.

;; With Magit you can do nearly everything that you can do when using Git
;; on the command-line, but at greater speed and while taking advantage
;; of advanced features that previously seemed too daunting to use on a
;; daily basis.  Many users will find that by using Magit they can become
;; more effective Git user.

  "Whether to bind some Magit commands in the global keymap.

If this variable is non-nil, then the following bindings may
be added to the global keymap.  The default is t.

key             binding
---             -------
C-x g           magit-status
C-x M-g         magit-dispatch
C-c M-g         magit-file-dispatch

These bindings may be added when `after-init-hook' is run.
Each binding is added if and only if at that time no other key
is bound to the same command and no other command is bound to
the same key.  In other words we try to avoid adding bindings
that are unnecessary, as well as bindings that conflict with
other bindings.

Adding the above bindings is delayed until `after-init-hook'
is called to allow users to set the variable anywhere in their
init file (without having to make sure to do so before `magit'
is loaded or autoloaded) and to increase the likelihood that
all the potentially conflicting user bindings have already
been added.

To set this variable use either `setq' or the Custom interface.
Do not use the function `customize-set-variable' because doing
that would cause Magit to be loaded immediately when that form
is evaluated (this differs from `custom-set-variables', which
doesn't load the libraries that define the customized variables).

Setting this variable to nil has no effect if that is done after
the key bindings have already been added.

We recommend that you bind \"C-c g\" instead of \"C-c M-g\" to
`magit-file-dispatch'.  The former is a much better binding
but the \"C-c <letter>\" namespace is strictly reserved for
users; preventing Magit from using it by default.

Also see info node `(magit)Commands for Buffers Visiting Files'."

If this comes as a surprise to you, because you do actually have
a newer version installed, then that probably means that the
older version happens to appear earlier on the `$PATH'.  If you
always start Emacs from a shell, then that can be fixed in the
shell's init file.  If you start Emacs by clicking on an icon,
or using some sort of application launcher, then you probably
have to adjust the environment as seen by graphical interface.
