+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+addresses, without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit,

+prompted for a value in the minibuffer.  Many values have completions,
+so don't hesitate to press @key{TAB} key.  Multiple values (for example,
+packages or lint checkers) should be separated by commas.
+
+After specifying all options and switches for a command, you may choose
+one of the available actions.  The following default actions are
+available for all commands:
+
+@itemize
+
+@item
+Run the command in the Guix REPL.  It is faster than running
+@code{guix@tie{}@dots{}} command directly in shell, as there is no

+
+@item
+Run the command in a shell buffer.  You can set

+you want to use.

+
+@end itemize
+
+Several commands (@command{guix graph}, @command{guix system shepherd-graph}
+and @command{guix system extension-graph}) also have a ``View graph''
+action, which allows you to view a generated graph using @command{dot}
+command (specified by @code{guix-dot-program} variable).  By default a
+PNG file will be saved in @file{/tmp} directory and will be opened
+directly in Emacs.  This behavior may be changed with the following
+variables:
+
+@table @code
+
+@item guix-find-file-function
+Function used to open a generated graph.  If you want to open a graph in
+an external program, you can do it by modifying this variable---for

+(@pxref{Top,,, org, The Org Manual}):
+
+@example
+(setq guix-find-file-function 'org-open-file)
+(add-to-list 'org-file-apps '("\\.png\\'" . "sxiv %s"))
+@end example
+
+@item guix-dot-default-arguments
+Command line arguments to run @command{dot} command.  If you change an
+output format (for example, into @code{-Tpdf}), you also need to change
+the next variable.

+@item guix-dot-file-name-function
+Function used to define a name of the generated graph file.  Default
+name is @file{/tmp/guix-emacs-graph-XXXXXX.png}.

+
+;;; Commentary:
+
+;; This file provides a magit-like popup interface for running guix
+;; commands in Guix REPL.  The entry point is "M-x guix".  When it is
+;; called the first time, "guix --help" output is parsed and
+;; `guix-COMMAND-action' functions are generated for each available guix
+;; COMMAND.  Then a window with these commands is popped up.  When a
+;; particular COMMAND is called, "guix COMMAND --help" output is parsed,
+;; and a user get a new popup window with available options for this
+;; command and so on.
+
+;; To avoid hard-coding all guix options, actions, etc., as much data is
+;; taken from "guix ... --help" outputs as possible.  But this data is
+;; still incomplete: not all long options have short analogs, also
+;; special readers should be used for some options (for example, to
+;; complete package names while prompting for a package).  So after
+;; parsing --help output, the arguments are "improved".  All arguments
+;; (switches, options and actions) are `guix-command-argument'
+;; structures.
+
+;; Only "M-x guix" command is available after this file is loaded.  The
+;; rest commands/actions/popups are generated on the fly only when they
+;; are needed (that's why there is a couple of `eval'-s in this file).
+
+;; COMMANDS argument is used by many functions in this file.  It means a
+;; list of guix commands without "guix" itself, e.g.: ("build"),
+;; ("import" "gnu").  The empty list stands for the plain "guix" without
+;; subcommands.
+
+;; All actions in popup windows are divided into 2 groups:
+;;
+;; - 'Popup' actions - used to pop up another window.  For example, every
+;;   action in the 'guix' or 'guix import' window is a popup action.  They
+;;   are defined by `guix-command-define-popup-action' macro.
+;;
+;; - 'Execute' actions - used to do something with the command line (to
+;;   run a command in Guix REPL or to copy it into kill-ring) constructed
+;;   with the current popup.  They are defined by
+;;   `guix-command-define-execute-action' macro.
