=head1 ERROR HANDLING
-Perltidy will return with an error flag indicating if the process had to be
-terminated early due to errors in the input parameters. This can happen for
-example if a parameter is misspelled or given an invalid value. The calling
-program should check this flag because if it is set the destination stream will
-be empty or incomplete and should be ignored. Error messages in the B<stderr>
-stream will indicate the cause of any problem.
-
-If the error flag is not set then perltidy ran to completion. However there
-may still be warning messages in the B<stderr> stream related to control
-parameters, and there may be warning messages in the B<errorfile> stream
-relating to possible syntax errors in the source code being tidied.
+An exit value of 0, 1, or 2 is returned by perltidy to indicate the status of the result.
+
+A exit value of 0 indicates that perltidy ran to completion with no error messages.
+
+An exit value of 1 indicates that the process had to be terminated early due to
+errors in the input parameters. This can happen for example if a parameter is
+misspelled or given an invalid value. The calling program should check for
+this flag because if it is set the destination stream will be empty or
+incomplete and should be ignored. Error messages in the B<stderr> stream will
+indicate the cause of any problem.
+
+An exit value of 2 indicates that perltidy ran to completion but there there
+are warning messages in the B<stderr> stream related to parameter errors or
+conflicts and/or warning messages in the B<errorfile> stream relating to
+possible syntax errors in the source code being tidied.
In the event of a catastrophic error for which recovery is not possible
B<perltidy> terminates by making calls to B<croak> or B<confess> to help the
