+# we convert csv files into a simplified interchange format:
+# text characters separated by tabs! we escape tabs, newlines, and backslashes
+# into \t, \n, and \\.
+
+# these functions process on standard input and standard output.
+# we allow CR LFs in input but we don't output them by default.
+
+# see csv.sh for an unminified version.
