Use the 3.0 module name to avoid spurious warnings.

Found them using::

  find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done

(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well.  If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)

(with one small bugfix in bgen/bgen/scantools.py)

This replaces string module functions with string methods
for the stuff in the Tools directory. Several uses of
string.letters etc. are still remaining.

This uses cgi.parse_header() in Checker.checkforhtml(), so that
webchecker recognises the mime type text/html even if options
are specified.

The cause seems to be that when a file URL doesn't exist,
urllib.urlopen() raises OSError instead of IOError.  Simply add this
to the except clause.  Not elegant, but effective. :-)

self.parser to be None; in that case don't dereference it in
getnames().

The robotparser.py module currently lives in Tools/webchecker.  In
preparation for its migration to Lib, I made the following changes:

    * renamed the test() function _test
    * corrected the URLs in _test() so they refer to actual documents
    * added an "if __name__ == '__main__'" catcher to invoke _test()
      when run as a main program
    * added doc strings for the two main methods, parse and can_fetch
    * replaced usage of regsub and regex with corresponding re code

files.  Removed Sam's "SLB" change comments; otherwise this is the
same as wcnew.py.

# and removed trailing whitespace.

- same trick with "import wcnew; webchecker = wcnew" as above
- updated readhtml() method to handle pair representation; used
  new name suppression infrastructure from wcnew.py to suppress
  processing name anchors

[And untabified --GvR]

- added -t and -a arguments
- added "import wcnew; webchecker = wcnew" in place of "import
  webchecker" (I assume that if you're happy with the changes, you'll
  just replace webchecker.py with wcnew.py, but if I were to do that,
  the diffs would be incomprehensible)
- fixed buggy -v argument (I think you got out of sync with the
  way verbosity was handled in webchecker vs. wcgui between 1.5 and
  1.5.2)
- made -v actually do something by adding a call to c.setflags()
  (probably the same problem as above)
- updated references to URLs to accommodate wcnew.py's pair
  representation; added appropriate calls to format_url() to handle
  display; added argument to ListPanel() initialization to provide
  access to format_url()

[And untabified --GvR]

- same fixes from webchecker.py
- incorporated small diff between current webchecker.py and 1.5.2
- fixed bug where "extra roots" added with the -t argument were being
  checked as real roots, not just as possible continuations
- added -a argument to suppress checking of name anchors

[And untabified --GvR]

- forced new done origins to set errors if they're in self.bad (fixes
  bug where only the first of a number of errorful references to a
  link is reported under some circumstances)
- suppressed adding duplicates to self.todo list (cleans up printout
  in wcgui details)

file URLs.

Unfortunately his code breaks wcgui.py in a way that's not easy
to fix.  I expect that this is a temporary situation --
eventually Sam's changes will be merged back in.
(The changes add a -t option to specify exceptions to the -x
option, and explicit checking for #foo style fragment ids.)

(The alternative would be to call self.checker.note() but since
self.checker might be None that's not quite right.
