+""" Utility for parsing HTML entity definitions available from:
+
+      http://www.w3.org/ as e.g.
+      http://www.w3.org/TR/REC-html40/HTMLlat1.ent
+
+    Input is read from stdin, output is written to stdout in form of a
+    Python snippet defining a dictionary "entitydefs" mapping literal
+    entity name to character or numeric entity.
