#
# The Perl::Tidy::Diagnostics class writes the DIAGNOSTICS file, which is
# useful for program development.
#
# Only one such file is created regardless of the number of input
# files processed.  This allows the results of processing many files
# to be summarized in a single file.

# Output messages go to a file named DIAGNOSTICS, where
# they are labeled by file and line.  This allows many files to be
# scanned at once for some particular condition of interest.  It was
# particularly useful for developing guessing strategies.
