Mass Deface
" is also
given, it specifies the extension for the backup file, and the backup
file remains around; by default, the extension is ".bak" and it is
deleted when the output file is closed. In-place filtering is
disabled when standard input is read. XXX The current implementation
does not work for MS-DOS 8+3 filesystems.
Performance: this module is unfortunately one of the slower ways of
processing large numbers of input lines. Nevertheless, a significant
speed-up has been obtained by using readlines(bufsize) instead of
readline(). A new keyword argument, bufsize=N, is present on the
input() function and the FileInput() class to override the default
buffer size.
XXX Possible additions:
- optional getopt argument processing
- isatty()
- read(), read(size), even readlines()

Create an instance of the FileInput class. The instance will be used
as global state for the functions of this module, and is also returned
to use during iteration. The parameters to this function will be passed
along to the constructor of the FileInput class.

Close the current file so that the next iteration will read the first
line from the next file (if any); lines not read from the file will
not count towards the cumulative line count. The filename is not
changed until after the first line of the next file has been read.
Before the first line has been read, this function has no effect;
it cannot be used to skip the first file. After the last line of the
last file has been read, this function has no effect.

Class FileInput is the implementation of the module; its methods
filename(), lineno(), fileline(), isfirstline(), isstdin(), fileno(),
nextfile() and close() correspond to the functions of the same name
in the module.
In addition it has a readline() method which returns the next
input line, and a __getitem__() method which implements the
sequence behavior. The sequence must be accessed in strictly
sequential order; random access and readline() cannot be mixed.
