;;; Commentary:
|
|
|
|
;; There is nothing to be done or configured in order to use this
|
|
;; module, other than to select it by customizing the variable
|
|
;; `eshell-modules-list'. It will then display a version information
|
|
;; message whenever Eshell is loaded.
|
|
;;
|
|
;; This code is only an example of a how to write a well-formed
|
|
;; extension module for Eshell. The better way to display login text
|
|
;; is to use the `eshell-script' module, and to echo the desired
|
|
;; strings from the user's `eshell-login-script' file.
|
|
;;
|
|
;; There is one configuration variable, which demonstrates how to
|
|
;; properly define a customization variable in an extension module.
|
|
;; In this case, it allows the user to change the string which
|
|
;; displays at login time.
