;;; Author: Ludovic Court�s
;;;
;;; Commentary:
;;;
;;; This (fake) module defines a macro called `define-skribe-module' which
;;; allows to package Skribe code (which uses Skribe built-ins and most
;;; importantly a Skribe syntax) as a Guile module. This module
;;; automatically exports the macro as a core binding so that future
;;; `use-modules' referring to Skribe modules will work as expected.
;;;
;;; Code:
(define *skribilo-user-imports*
;; List of modules that should be imported by any good Skribilo module.
'((srfi srfi-1) ;; lists
(srfi srfi-13) ;; strings
