+
+#Latest version. My sort passes all tests because I wrote it.
+#We differ only on 25E and 25H.
+#(I found at least one bug in constructing test 25, and was driven
+#to rewrite field parsing to clarify it.)
+#
+#In 25E, -k2.3,2.1b, the fields are not necessarily out of order.
+#Even if they were, it would be legal (11752-3), although certainly
+#justification for warning.
+#
+#On 25H, your answer is as defensible as mine. (Our suggestion
+#*1 backs mine.)

+# Tests for the Unix sort utility
+# Test Posix features except for locale.
+# Test some nonstandard features if present.
+
+# Other tests should be made for files too big to fit in memory.

+# Initialize switches for nonstandard features.
+# Use parenthesized settings for supported features.
