+# Revision history

+# 1.0 -- 2002/02/20 -- initial release
+#
+# Description
+# -----------
+# txt2latex assists in translation from ASCII text to LaTeX by escaping
+# special characters and "fixing" quote marks (using English conventions).
+# Reads from standard input and writes to standard output.
+# Any "unfixed" double quotes are reported on standard error.
+#
+# If there is a demand, I will add command-line options allowing
+# customization or suppression of the document header/footer, and use of
+# non-English quotation marks (e.g., "` and "').
