-;; It creates some functions named like "wg-buf-...", "wg-session-..."
+;; So if you have "(wg-defstruct wg session ...)" - then you have
+;; `wg-session-file-name' and other defined fields.
 ;;
 ;; To get a value you can use:
-;; (wg-session-... (wg-current-session))
-;; Like:
-;; (wg-session-file-name (wg-current-session))
-;; (wg-workgroup-parameters (wg-current-workgroup))
+;;   (wg-session-... (wg-current-session))

+;; Example:
+;;   (wg-session-file-name (wg-current-session))
+;;   (wg-workgroup-parameters (wg-current-workgroup))
