Tidy Configuration Options
==========================
 Use Tidy's configuration options as command line arguments in the form
 of "--some-option <value>", for example, "--indent-with-tabs yes".

 You can also specify a file containing configuration options with the
 -config <file> directive, or in one or more files specific to your
 environment (see next section).

 For a list of all configuration options, use "-help-config" or refer
 to the man page (if your OS has one).

Configuration Files
===================
 If your environment has an $HTML_TIDY variable set to point to a Tidy
 configuration file, then Tidy will attempt to use it.

 Additionally, Tidy will automatically attempt to use configuration specified
 in these files, if present:

  /etc/tidy.conf
  ~/.tidyrc

 Use "-help-env" for more information about how you can use the environment.
 to specify Tidy options.

Other
=====
 Input/Output default to stdin/stdout respectively.

 Single letter options apart from -f may be combined
 as in:  tidy -f errs.txt -imu foo.html
