-
-;;; 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.
