| /** |
| * Matches a typical Copyright header line only based on a regex pattern |
| * which allows for one (starting) year or year range, and a |
| * configurable copyright owner. |
| * <br> |
| * <br>The matching is done case insensitive<br> |
| * <br> |
| * Example supported Copyright header lines, using copyright owner "FooBar" |
| * <ul> |
| * <li>* Copyright 2010 FooBar. *</li> |
| * <li>* Copyright 2010-2012 FooBar. *</li> |
| * <li>*copyright 2012 foobar*</li> |
| * </ul> |
| * <p>Note also that the copyright owner is appended to the regex pattern, so |
| * can support additional regex but also requires escaping where needed,<p> |
| * e.g. use "FooBar \(www\.foobar\.com\)" for matching "FooBar (www.foobar.com)"<p> |
| * |
| * @since Rat 0.9 |
