-     * bad decisions due to an error.
-     *
-     * If the root is not near one of the endpoints, then we will
-     * only have a slight inaccuracy in calculating the x intercept

-     * case are not as accurate as they could be, they are not
-     * disastrously inaccurate either.
-     *
-     * On the other hand, if the error happens near one end of
-     * the curve, then our processing to reject values outside
-     * of the t=[0,1] range will fail and the results of that
-     * failure will be disastrous since for an entire horizontal

-     * the crossings and get a wrong answer for all of them, even
-     * when they are clearly and obviously inside or outside the
-     * curve.
-     *
-     * To work around this problem, we try a couple of Newton-Raphson
-     * iterations to see if the true root is closer to the endpoint
-     * or further away.  If it is further away, then we can stop
-     * since we know we are on the right side of the endpoint.  If
-     * we change direction, then either we are now being dragged away
-     * from the endpoint in which case the first condition will cause
-     * us to stop, or we have passed the endpoint and are headed back.
-     * In the second case, we simply evaluate the slope at the
-     * endpoint itself and place ourselves on the appropriate side

 /**
- * A file reference that locates a file using a system dependent path. The file
- * is not required to exist.
- *
- * <p> On many platforms a <em>path</em> is the means to locate and access files
- * in a file system. A path is hierarchical and composed of a sequence of
- * directory and file name elements separated by a special separator or
- * delimiter.
- *
- * <h4>Path operations</h4>
+ * An object that may be used to locate a file in a file system. It will
+ * typically represent a system dependent file path.
  *
- * <p> A system dependent path represented by this class is conceptually a
- * sequence of name elements and optionally a <em>root component</em>. The name
- * that is <em>farthest</em> from the root of the directory hierarchy is the
- * name of a file or directory. The other elements are directory names. The root
- * component typically identifies a file system hierarchy. A {@code Path} can
- * represent a root, a root and a sequence of names, or simply one or more name
- * elements. It defines the {@link #getName() getName}, {@link #getParent
- * getParent}, {@link #getRoot getRoot}, and {@link #subpath subpath} methods
- * to access the components or a subsequence of its name elements.
+ * <p> A {@code Path} represents a path that is hierarchical and composed of a
+ * sequence of directory and file name elements separated by a special separator
+ * or delimiter. A <em>root component</em>, that identifies a file system
+ * hierarchy, may also be present. The name element that is <em>farthest</em>
+ * from the root of the directory hierarchy is the name of a file or directory.
+ * The other name elements are directory names. A {@code Path} can represent a
+ * root, a root and a sequence of names, or simply one or more name elements.
+ * A {@code Path} is considered to be an <i>empty path</i> if it consists
+ * solely of one name element that is empty. Accessing a file using an
+ * <i>empty path</i> is equivalent to accessing the default directory of the
+ * file system. {@code Path} defines the {@link #getFileName() getFileName},
+ * {@link #getParent getParent}, {@link #getRoot getRoot}, and {@link #subpath
+ * subpath} methods to access the path components or a subsequence of its name
+ * elements.
  *
  * <p> In addition to accessing the components of a path, a {@code Path} also
- * defines {@link #resolve(Path) resolve} and {@link #relativize relativize}
- * operations. Paths can also be {@link #compareTo compared}, and tested
- * against each other using using the {@link #startsWith startsWith} and {@link
- * #endsWith endWith} methods.
- *
- * <h4>File operations</h4>
+ * defines the {@link #resolve(Path) resolve} and {@link #resolveSibling(Path)
+ * resolveSibling} methods to combine paths. The {@link #relativize relativize}
+ * method that can be used to construct a relative path between two paths.
+ * Paths can be {@link #compareTo compared}, and tested against each other using
+ * the {@link #startsWith startsWith} and {@link #endsWith endWith} methods.
  *
- * <p> A {@code Path} is either <em>absolute</em> or <em>relative</em>. An
- * absolute path is complete in that does not need to be combined with another
- * path in order to locate a file. All operations on relative paths are first
- * resolved against a file system's default directory as if by invoking the
- * {@link #toAbsolutePath toAbsolutePath} method.
- *
- * <p> In addition to the operations defined by the {@link FileRef} interface,
- * this class defines the following operations:
+ * <p> This interface extends {@link Watchable} interface so that a directory
+ * located by a path can be {@link #register registered} with a {@link
+ * WatchService} and entries in the directory watched. </p>
  *
- * <ul>
- *   <li><p> The {@link #newByteChannel newByteChannel} method
- *     may be used to open a file and obtain a byte channel for reading or
- *     writing. </p></li>
- *   <li><p> Files may be {@link #createFile(FileAttribute[]) created}, or
- *     directories may be {@link #createDirectory(FileAttribute[]) created}.
- *     </p></li>
- *   <li><p> The {@link #delete delete} method may be used to delete a file.
- *     </p></li>
- *   <li><p> The {@link #checkAccess checkAccess} method may be used to check
- *     the existence or accessibility of a file. </p></li>
- *   <li><p> The {@link #isSameFile isSameFile} method may be used to test if
- *     two file references locate the same file. </p></li>
- *   <li><p> The {@link #getFileStore getFileStore} method may be used to
- *     obtain the {@link FileStore} representing the storage where a file is
- *     located. </p></li>
- *   <li><p> Directories can be {@link #newDirectoryStream opened} so as to
- *      iterate over the entries in the directory. </p></li>
- *   <li><p> Files can be {@link #copyTo(Path,CopyOption[]) copied} or
- *     {@link #moveTo(Path,CopyOption[]) moved}. </p></li>
- *   <li><p> Symbolic links may be {@link #createSymbolicLink created}, or the
- *     target of a symbolic link may be {@link #readSymbolicLink read}. </p></li>
- *   <li><p> The {@link #toRealPath real} path of an existing file may be
- *     obtained. </li></p>
- * </ul>
+ * <p> <b>WARNING:</b> This interface is only intended to be implemented by
+ * those developing custom file system implementations. Methods may be added to
+ * this interface in future releases. </p>
  *
- * <p> This class implements {@link Watchable} interface so that a directory
- * located by a path can be {@link #register registered} with a {@link WatchService}.

- * <h4>File attributes</h4>
- *
- * In addition to the {@link #setAttribute setAttribute} and {@link #getAttribute
- * getAttribute} methods, the <a href="attribute/package-summary.html">{@code
- * java.nio.file.attribute}</a> package provides type-safe and efficient access
- * to file attributes or <em>meta-data</em> associated with files. The {@link
- * Attributes Attributes} class defines methods that operate on or return file
- * attributes. For example, the file type, size, timestamps, and other
- * <em>basic</em> meta-data are obtained, in bulk, by invoking the {@link
- * Attributes#readBasicFileAttributes Attributes.readBasicFileAttributes} method:
+ * <a name="interop"><h4>Accessing Files</h4></a>
+ * <p> Paths may be used with the {@link Files} class to operate on files,
+ * directories, and other types of files. For example, suppose we want a {@link
+ * java.io.BufferedReader} to read text from a file "{@code access.log}". The
+ * file is located in a directory "{@code logs}" relative to the current working
+ * directory and is UTF-8 encoded.
  * <pre>
- *     Path file = ...
- *     BasicFileAttributes attrs = Attributes.readBasicFileAttributes(file);
+ *     Path path = FileSystems.getDefault().getPath("logs", "access.log");
+ *     BufferReader reader = Files.newBufferedReader(path, Charset.forName("UTF-8"));
  * </pre>
  *
  * <a name="interop"><h4>Interoperability</h4></a>
- *
- * <p> Paths created by file systems associated with the default {@link
+ * <p> Paths associated with the default {@link
  * java.nio.file.spi.FileSystemProvider provider} are generally interoperable
  * with the {@link java.io.File java.io.File} class. Paths created by other
  * providers are unlikely to be interoperable with the abstract path names
- * represented by {@code java.io.File}. The {@link java.io.File#toPath
- * File.toPath} method may be used to obtain a {@code Path} from the abstract
- * path name represented by a {@code java.io.File java.io.File} object. The
- * resulting {@code Path} can be used to operate on the same file as the {@code
- * java.io.File} object.
- *
- * <p> Path objects created by file systems associated with the default
- * provider are interoperable with objects created by other file systems created
- * by the same provider. Path objects created by file systems associated with
- * other providers may not be interoperable with other file systems created by
- * the same provider. The reasons for this are provider specific.
+ * represented by {@code java.io.File}. The {@link java.io.File#toPath toPath}
+ * method may be used to obtain a {@code Path} from the abstract path name
+ * represented by a {@code java.io.File} object. The resulting {@code Path} can
+ * be used to operate on the same file as the {@code java.io.File} object. In
+ * addition, the {@link #toFile toFile} method is useful to construct a {@code
+ * File} from the {@code String} representation of a {@code Path}.
  *
