Summary: dest parameter in optparse
Initial Comment:
When using the "callback" action, optparse requires
that you STILL specify a "dest" parameter, though it is
not required or used by the option parser.
In fact, if you do not include the "dest" parameter, your
options will still work properly, but optparse will
generate an exception when calling the "--help" option.
Not specifying a "dest" parameter will result in the
following Exception when using the default "--help" or "-
h" option:
File "c:\Python23\lib\optparse.py", line 229, in
format_option_strings
metavar = option.metavar or option.dest.upper()
AttributeError: 'NoneType' object has no attribute 'upper'
<workaround>
by simply adding a bogus bug, the --help / -h option
works properly even though the dest isn't actually used.
</workaround>

No response from original poster after almost a year, so I'm
assuming that I did indeed fix this bug in Optik 1.5 /
Python 2.4.

ahmado -- please check if this bug is still present in
Python 2.4 / Optik 1.5. If you do not respond in a week or
two, I will assume that the bug is fixed and close this report.

I'm pretty sure I fixed this in Optik 1.5 / Python 2.4. Can
you 1) verify if the bug is still there in Python 2.4 and 2)
if so, supply a small script demonstrating the problem?
