# A helper to use instead the builtin IO class to read files in
# correct encoding.
#
# By default in Ruby 1.9 the encoding is auto-detected, which can
# have surprising results. So in here we read in all files in UTF-8
# (the default) or in some other encoding specified through --encoding
# option and convert it to UTF-8 internally.
#
# We also allow for UTF-8 byte order mark.
class IO
@@encoding = "BOM|UTF-8"
# Configures the encoding from command line options.
def self.configure(opts)

end

# When it's different from UTF-8, the input will be converted to UTF-8.
