<!--
  Checkstyle configuration for Commons FileUpload. FileUpload uses the Sun
  coding guidelines, so this file is almost the same as Maven's sun_checks.xml
  file. The only changes from that file are:

    - Use a RegexpHeader check instead of a regular Header check, since the
      copyright years can vary per source file.

    - Disable the HiddenField module, since FileUpload has always used the
      "this.foo = foo" pattern, which is not recognised by this module.

    - Disable the DesignForExtension module, since fixing those complaints
      would result in backwards incompatible API changes.

    - Disable the FinalParameters module, since fixing those complaints
      would result in backwards incompatible API changes.

  Checkstyle configuration that checks the sun coding conventions from:

    - the Java Language Specification at
      http://java.sun.com/docs/books/jls/second_edition/html/index.html

    - the Sun Code Conventions at http://java.sun.com/docs/codeconv/

    - the Javadoc guidelines at
      http://java.sun.com/j2se/javadoc/writingdoccomments/index.html

    - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html

    - some best practices

  Checkstyle is very configurable. Be sure to read the documentation at
  http://checkstyle.sf.net (or in your downloaded distribution).

  Most Checks are configurable, be sure to consult the documentation.

  To completely disable a check, just comment it out or delete it from the file.

  Finally, it is worth reading the documentation.
