+# A slides file should populate the variable slides with
+# a list of tuples.  Each tuple should have:
+#
+#       - Slide content
+#       - User data
+#       - Canvas width
+#       - Canvas height
+#
+# Slide content can be a string, a list of strings,
+# a function returning one of those, or a generator
+# yielding strings.  The user data should be a dictionary or
+# None, and is both used to communicate options to the
+# renderer and to pass extra options to the theme functions.
+#
+# A function-based slide content will be passed a renderer object.
+# Renderer is an object similar to a cairo.Context and
+# pangocairo.CairoContext but has its own methods too.
+# The more useful of them here are put_text, put_image, and
+# set_allocation.  See their pydocs.
