We always wrote a pair of lines to the Wise install.log telling it to
delete the Tools and Lib directories at uninstall time.  However,
under the old version of Wise, they didn't actually do anything.  Under
the new version, they work as advertised, and even delete files users
added.
Got rid of those, and replaced them with similar uninstall cmds that
get rid of all .pyc and .pyo files (whether or not the installer created
them).  This works nicely!  It still tears down the directory structure,
except for those directories needed to get to any non-.pyc/o file(s) the
user may have added.
