  *  Various constants for the methods in File can be found in File::Constants.
+ *
+ *  == What's Here
+ *
+ *  First, what's elsewhere. \Class \File:
+ *
+ *  - Inherits from class IO -- in particular, methods for creating,
+ *    reading, and writing files.
+ *  - Includes module FileTest.
+ *
+ *  Here, Class \File provides methods that are useful for:
+ *
+ *  - {Creating}[#class-File-label-Creating]
+ *  - {Querying}[#class-File-label-Querying]
+ *  - {Settings}[#class-File-label-Settings]
+ *  - {Other}[#class-File-label-Other]
+ *
+ *  === Creating
+ *
+ *  - ::new:: Opens the file at the given path; returns the file.
+ *  - ::open:: Same as ::new, but when given a block will yield the file to the block,
+ *             and close the file upon exiting the block.
+ *  - ::link:: Creates a new name for an existing file using a hard link.
+ *  - ::mkfifo:: Returns the FIFO file created at the given path.
+ *  - ::symlink:: Creates a symbolic link for the given file path.
+ *
+ *  === Querying

+ *  - ::path:: Returns the string representation of the given path.
+ *  - ::readlink:: Returns the path to the file at the given symbolic link.
+ *  - ::realdirpath:: Returns the real path for the given file path,
+ *                    where the last component need not exist.
+ *  - ::realpath:: Returns the real path for the given file path,
+ *                 where all components must exist.
+ *  - ::split:: Returns an array of two strings: the directory name and basename
+ *              of the file at the given path.

+ *  - ::birthtime:: Returns a \Time  for the creation of the given file.
+ *  - ::ctime:: Returns a \Time  for the metadata change of the given file.
+ *  - ::mtime:: Returns a \Time for the most recent data modification to
+ *              the content of the given file.
+ *  - #atime:: Returns a \Time for the most recent access to +self+.
+ *  - #birthtime:: Returns a \Time  the creation for +self+.
+ *  - #ctime:: Returns a \Time for the metadata change of +self+.
