-# f = posixfile.open(filename, [mode, [bufsize]])
-#	will create a new posixfile object
-#
-# f = posixfile.fileopen(fileobject)
-#	will create a posixfile object from a builtin file object
-#
-# f.file()
-#	will return the original builtin file object
-#
-# f.dup()
-#	will return a new file object based on a new filedescriptor
-#
-# f.dup2(fd)
-#	will return a new file object based on the given filedescriptor
-#
-# f.flags(mode)
-#	will turn on the associated flag (merge)
-#	mode can contain the following characters:
-#
-#   (character representing a flag)
-#	a	append only flag
-#	c	close on exec flag
-#	n	no delay flag
-#	s	synchronization flag
-#   (modifiers)
-#	!	turn flags 'off' instead of default 'on'
-#	=	copy flags 'as is' instead of default 'merge'
-#	?	return a string in which the characters represent the flags
-#		that are set
-#
-#	note: - the '!' and '=' modifiers are mutually exclusive.
-#	      - the '?' modifier will return the status of the flags after they
-#		have been changed by other characters in the mode string
-#
-# f.lock(mode [, len [, start [, whence]]])
-#	will (un)lock a region
-#	mode can contain the following characters:
-#
-#   (character representing type of lock)
-#	u	unlock
-#	r	read lock
-#	w	write lock
-#   (modifiers)
-#	|	wait until the lock can be granted
-#	?	return the first lock conflicting with the requested lock
-#		or 'None' if there is no conflict. The lock returned is in the
-#		format (mode, len, start, whence, pid) where mode is a
-#		character representing the type of lock ('r' or 'w')
-#
-#	note: - the '?' modifier prevents a region from being locked; it is
-#		query only
