This module defines a number of utilities for use by CGI scripts
written in Python.
The global variable maxlen can be set to an integer indicating the maximum size
of a POST request. POST requests larger than this size will result in a
ValueError being raised during parsing. The default value of this variable is 0,
meaning the request size is unlimited.

Even though this function is called initlog(), you should always
use log(); log is a variable that is set either to initlog
(initially), to dolog (once the log file has been opened), or to
nolog (when logging is disabled).
The first argument is a format string; the remaining arguments (if
any) are arguments to the % operator, so e.g.
log("%s: %s", "a", "b")
will write "a: b" to the log file, followed by a newline.
If the global logfp is not None, it should be a file object to
which log data is written.
If the global logfp is None, the global logfile may be a string
giving a filename to open, in append mode. This file should be
world writable!!! If the file can't be opened, logging is
silently disabled (since there is no safe place where we could
send an error message).
z7cgi.log() is deprecated as of 3.10. Use logging instead )

Arguments, all optional:
fp : file pointer; default: sys.stdin.buffer
environ : environment dictionary; default: os.environ
keep_blank_values: flag indicating whether blank values in
percent-encoded forms should be treated as blank strings.
A true value indicates that blanks should be retained as
blank strings. The default false value indicates that
blank values are to be ignored and treated as if they were
not included.
strict_parsing: flag indicating what to do with parsing errors.
If false (the default), errors are silently ignored.
If true, errors raise a ValueError exception.
separator: str. The symbol to use for separating the query arguments.
Defaults to &.

a Parse multipart input.
Arguments:
fp : input file
pdict: dictionary containing other parameters of content-type header
encoding, errors: request encoding and error handler, passed to
FieldStorage
Returns a dictionary just like parse_qs(): keys are the field names, each
value is a list of values for that field. For non-file fields, the value
is a list of strings.
