The bdist_wininst.py command has been recreated after wininst.exe

has been changed to include an uninstaller.
I forgot to mention in the uninstaller checkin that the logfile
name (used for uninstalling) has been changed from
<module>.log to <module>-wininst.log. This should prevent
conflicts with a distutils logfile serving the same purpose.

The short form of the --bdist-dir (-d) option has been removed
because it caused conflicts with the short form of the --dist-dir
option.
