This line appears in test_zlib.py:
co = zlib.compressobj(2, 8, -12, 9, 1)
A few others also:
zlib.compressobj(1, 8, 0)
co = zlib.compressobj(8, 8, -15)
The only call I see documented in
<YPathMV>Python21/Doc/lib/module-zlib.html
is
compressobj([level])
Of course, there are a lot of strings with 'compress'
to disambiguate visually and method-vs-function'ly,
so I may have missed it ;-)

BTW, a tip for NT newbies who may be trying to capture the stdout
output of a script interpreter on NT in a console ("DOS" ;-) window
(this is true for perl as well as python -- it's a windows shell
problem):
You have to invoke the interpreter explicitly. I.e.,
myScript.py > output_file
doesn't work. '.py' is recognized (assuming you have the
association set up, of course) and python is executed, but
the shell mechanism that runs the interpreter does not
do it in such a way that its output is captured by '>'
python myScript.py > output_file
_does_ work, and if you wrap your script in a ".cmd" it will
work. Note what happens: (Y*MV == Your * May Vary ;-)
YPMV>type myCmd.py
#myCmd.py
import sys
print "This is from myCmd.py"
for i in range(len(sys.argv)):
print i,':', sys.argv[i]
YPMV>myCmd.py one two > myCmd.py.out
YPMV>type myCmd.py.out
YPMV>dir myCmd.py.out
Volume in drive <YDriveMV> is <YDriveNameMV>
Volume Serial Number is <YSNMV>
Directory of <YDirMV>
<YDateMV> 0 myCmd.py.out
1 File(s) 0 bytes
<YFBMV> bytes free
YPMV>type myCmd.cmd
@REM myCmd.cmd wrapper for myCmd.py
@python myCmd.py %*
YPMV>myCmd.cmd one two > myCmd.cmd.out
YPMV>type myCmd.cmd.out
This is from myCmd.py
0 : myCmd.py
1 : one
2 : two
Someone worked out an extreme (naturally?) perl workaround
for this, but I didn't set it up, and forgot where it went.
I am not going to <YDirectionMV>grade from NT4 just for a
fix for that, even if they fix it. (Did they, yet?)

Re zlib-type things again:
Is there a module giving access to standard FAX-type
compression of monochrome graphics with bitmapped fonts?
Or FAX in general, for that matter? Are the fax algorithms
patented (i.e., is there a .gif-type situation)?
The only "fax" in the entire doc tree is
*** FILE acks.html ***
<td>Lele Gaifax</td>
