+	@doc:	file
+	@keyterms:
+		file object class, creating files
+	@title:
+		file class
+	@type:
+		class
+	@short:
+		I/O device that operates on files
+	@inherits:
+		[class]object[/class]
+	@description:
+		This object class provides access to files - basic I/O
+		operations, copying, removing etc...
+	@functions:
+		!fn: $setName(<file_name:string>)
+		Sets the file name to <file_name>. It does [b]not move[/b] the file,
+		it just changes the file the object is "pointing to". You can
+		not change names of already open files.[br]
+		See also: [classfnc]$open[/classfnc](),
+		[classfnc]$name[/classfnc]().
+		!fn: <string> $name()
+		Returns name set by [classfnc]$setName[/classfnc]().[br]
+		See also: [classfnc]$setName[/classfnc]().
+		!fn: $open(<mode1:string>, <mode2:string>)
+		Attempts to open the file in specified mode or modes "sum".
+		Valid modes are:[br]
+		[pre]
+		Raw          - raw, non-buffered access[br]
+		ReadOnly     - opens the file read-only[br]
+		WriteOnly    - opens the file write-only[br]
+		ReadWrite    - opens the file in read-write mode[br]
+		Append       - opens the file in append mode. The file index is set to the end of the file.[br]
+		Truncate     - truncates the file[br]
+		[/pre]
+		If you call this function without any parameters, the file is
+		opened in ReadOnly mode.[br]
+		When working with buffered files, data is not written directly
+		to the file at once. You must call [classfnc]$flush[/classfnc]() to force it.[br]
+		See also: [classfnc]$close[/classfnc](),
+		[classfnc]$flush[/classfnc]().
+		!fn: <boolean> $isOpen()
+		Returns '1' if the file is open, '0' otherwise.
+		!fn: $close()
+		Closes the file, flushing the buffers first.[br]
+		See also: [classfnc]$flush[/classfnc]().
+		!fn: $flush()
+		Flushes the file buffer to disk. Calling this after opening the
+		file in 'Raw' mode doesn't make much sense.[br]
+		See also: [classfnc]$open[/classfnc](),
+		[classfnc]$close[/classfnc]().
+		!fn: <integer> $size()
+		Returns current file size.
+		!fn: <boolean> $atEnd()
+		Returns '1' if you have reached end of the file, '0' otherwise.
+		[br]See also: [classfnc]$seek[/classfnc](),
+		[classfnc]$where[/classfnc]().
+		!fn: <integer> $where()
+		Returns current position in the file (file index).[br]
+		See also: [classfnc]$seek[/classfnc]().
+		!fn: $seek(<index:integer>)
+		Sets the file index to <index>.[br]
+		See also: [classfnc]$where[/classfnc](),
+		[classfnc]$atEnd[/classfnc]().
+		!fn: $putch(<char>)
+		Writes character <char> to the file and increments file
+		index.[br]
+		See also: [classfnc]$getch[/classfnc](),
+		[classfnc]$ungetch[/classfnc]().
+		!fn: <char> $getch()
+		Reads a character from the file and increments file index.[br]
+		See also: [classfnc]$putch[/classfnc](),
+		[classfnc]$ungetch[/classfnc]().
+		!fn: $ungetch(<char>)
+		Puts the character <char> back to the file and
+		decrements the file index. This is usually called to undo a
+		$getch() call.[br]
+		See also: [classfnc]$getch[/classfnc],
+		[classfnc]$putch[/classfnc]().
+		!fn: $readLine(<text_line:string>)
+		Reads a line of text from the file and increments file index.
+		!fn: $writeLine(<text_line:string>)
+		Appends a line of text to the end of the file.
+		$readBlock()
+		$writeBlock()
+		$writeHex()
+		$readHex()
