+Usage: $0 <expected-hint-file> <actual-hint-file>
+
+    Print differences between the hint information in the two files. The files
+    must in a CSV format delimited by '|'. The easiest way to obtain such a
+    file is to use hintextract.
+
+    The output is sorted lexigraphically in reverse order. If the arguments
+    are reversed, the new output can also be generated from the old one by
+    reversing the signs and sorting again in reverse order (under LC_ALL=C).
+    It only works with uncolored output.
+
+    Returns with a zero exit code under normal conditions, even when the hints
+    do not match.
