+/**
+ * <p>Class for scanning a directory for files/directories which match certain
+ * criteria.</p>
+ *
+ * <p>These criteria consist of selectors and patterns which have been specified.
+ * With the selectors you can select which files you want to have included.
+ * Files which are not selected are excluded. With patterns you can include
+ * or exclude files based on their filename.</p>
+ *
+ * <p>The idea is simple. A given directory is recursively scanned for all files
+ * and directories. Each file/directory is matched against a set of selectors,
+ * including special support for matching against filenames with include and
+ * and exclude patterns. Only files/directories which match at least one
+ * pattern of the include pattern list or other file selector, and don't match
+ * any pattern of the exclude pattern list or fail to match against a required
+ * selector will be placed in the list of files/directories found.</p>
+ *
+ * <p>When no list of include patterns is supplied, "**" will be used, which
+ * means that everything will be matched. When no list of exclude patterns is
+ * supplied, an empty list is used, such that nothing will be excluded. When
+ * no selectors are supplied, none are applied.</p>
+ *
+ * <p>The filename pattern matching is done as follows:
+ * The name to be matched is split up in path segments. A path segment is the
+ * name of a directory or file, which is bounded by
+ * <code>File.separator</code> ('/' under UNIX, '\' under Windows).
+ * For example, "abc/def/ghi/xyz.java" is split up in the segments "abc",
+ * "def","ghi" and "xyz.java".
+ * The same is done for the pattern against which should be matched.</p>
+ *
+ * <p>The segments of the name and the pattern are then matched against each
+ * other. When '**' is used for a path segment in the pattern, it matches
+ * zero or more path segments of the name.</p>
+ *
+ * <p>There is a special case regarding the use of <code>File.separator</code>s
+ * at the beginning of the pattern and the string to match:<br>
+ * When a pattern starts with a <code>File.separator</code>, the string
+ * to match must also start with a <code>File.separator</code>.
+ * When a pattern does not start with a <code>File.separator</code>, the
+ * string to match may not start with a <code>File.separator</code>.
+ * When one of these rules is not obeyed, the string will not
+ * match.</p>
+ *
+ * <p>When a name path segment is matched against a pattern path segment, the
+ * following special characters can be used:<br>
+ * '*' matches zero or more characters<br>
+ * '?' matches one character.</p>
+ *
+ * <p>Examples:
+ * <br>
+ * <code>"**\*.class"</code> matches all <code>.class</code> files/dirs in a directory tree.
+ * <br>
+ * <code>"test\a??.java"</code> matches all files/dirs which start with an 'a', then two
+ * more characters and then <code>".java"</code>, in a directory called test.
+ * <br>
+ * <code>"**"</code> matches everything in a directory tree.
+ * <br>
+ * <code>"**\test\**\XYZ*"</code> matches all files/dirs which start with <code>"XYZ"</code> and where
+ * there is a parent directory called test (e.g. <code>"abc\test\def\ghi\XYZ123"</code>).
+ * </p>
+ *
+ * <p>Case sensitivity may be turned off if necessary. By default, it is
+ * turned on.</p>
+ *
+ * <p>Example of usage:</p>
+ * <pre>
+ * String[] includes = {"**\\*.class"};
+ * String[] excludes = {"modules\\*\\**"};
+ * ds.setIncludes(includes);
+ * ds.setExcludes(excludes);
+ * ds.setBasedir(new File("test"));
+ * ds.setCaseSensitive(true);
+ * ds.scan();
+ *
+ * System.out.println("FILES:");
+ * String[] files = ds.getIncludedFiles();
+ * for (int i = 0; i < files.length; i++) {
+ * System.out.println(files[i]);
+ * }
+ * </pre>
+ * <p>This will scan a directory called test for .class files, but excludes all
+ * files in all proper subdirectories of a directory called "modules".</p>

-/**
- * <p>Class for scanning a directory for files/directories which match certain
- * criteria.</p>
- *
- * <p>These criteria consist of selectors and patterns which have been specified.
- * With the selectors you can select which files you want to have included.
- * Files which are not selected are excluded. With patterns you can include
- * or exclude files based on their filename.</p>
- *
- * <p>The idea is simple. A given directory is recursively scanned for all files
- * and directories. Each file/directory is matched against a set of selectors,
- * including special support for matching against filenames with include and
- * and exclude patterns. Only files/directories which match at least one
- * pattern of the include pattern list or other file selector, and don't match
- * any pattern of the exclude pattern list or fail to match against a required
- * selector will be placed in the list of files/directories found.</p>
- *
- * <p>When no list of include patterns is supplied, "**" will be used, which
- * means that everything will be matched. When no list of exclude patterns is
- * supplied, an empty list is used, such that nothing will be excluded. When
- * no selectors are supplied, none are applied.</p>
- *
- * <p>The filename pattern matching is done as follows:
- * The name to be matched is split up in path segments. A path segment is the
- * name of a directory or file, which is bounded by
- * <code>File.separator</code> ('/' under UNIX, '\' under Windows).
- * For example, "abc/def/ghi/xyz.java" is split up in the segments "abc",
- * "def","ghi" and "xyz.java".
- * The same is done for the pattern against which should be matched.</p>
- *
- * <p>The segments of the name and the pattern are then matched against each
- * other. When '**' is used for a path segment in the pattern, it matches
- * zero or more path segments of the name.</p>
- *
- * <p>There is a special case regarding the use of <code>File.separator</code>s
- * at the beginning of the pattern and the string to match:<br>
- * When a pattern starts with a <code>File.separator</code>, the string
- * to match must also start with a <code>File.separator</code>.
- * When a pattern does not start with a <code>File.separator</code>, the
- * string to match may not start with a <code>File.separator</code>.
- * When one of these rules is not obeyed, the string will not
- * match.</p>
- *
- * <p>When a name path segment is matched against a pattern path segment, the
- * following special characters can be used:<br>
- * '*' matches zero or more characters<br>
- * '?' matches one character.</p>
- *
- * <p>Examples:
- * <br>
- * <code>"**\*.class"</code> matches all <code>.class</code> files/dirs in a directory tree.
- * <br>
- * <code>"test\a??.java"</code> matches all files/dirs which start with an 'a', then two
- * more characters and then <code>".java"</code>, in a directory called test.
- * <br>
- * <code>"**"</code> matches everything in a directory tree.
- * <br>
- * <code>"**\test\**\XYZ*"</code> matches all files/dirs which start with <code>"XYZ"</code> and where
- * there is a parent directory called test (e.g. <code>"abc\test\def\ghi\XYZ123"</code>).
- * </p>
- *
- * <p>Case sensitivity may be turned off if necessary. By default, it is
- * turned on.</p>
- *
- * <p>Example of usage:</p>
- * <pre>
- * String[] includes = {"**\\*.class"};
- * String[] excludes = {"modules\\*\\**"};
- * ds.setIncludes(includes);
- * ds.setExcludes(excludes);
- * ds.setBasedir(new File("test"));
- * ds.setCaseSensitive(true);
- * ds.scan();
- *
- * System.out.println("FILES:");
- * String[] files = ds.getIncludedFiles();
- * for (int i = 0; i < files.length; i++) {
- * System.out.println(files[i]);
- * }
- * </pre>
- * <p>This will scan a directory called test for .class files, but excludes all
- * files in all proper subdirectories of a directory called "modules".</p>
