+ ;;; 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.
