-;;; A reader for the Skribe syntax, i.e. roughly R5RS Scheme plus DSSSL-style
-;;; keywords and sk-exps (expressions introduced using a square bracket).
+;;; This module provides syntactic candy for Skribilo modules, i.e., a syntax
+;;; similar to Guile's default syntax with a few extensions, plus various
+;;; convenience macros.
