You may also need to remove scripts from the Python24\Scripts directory
that have 'schevo' as the prefix rather than 'evo', such as 'schevo.exe'
and 'schevo_hotshot.exe'.  This was an attempt that didn't quite work
due to a limitation of setuptools.  But I've been sort of fond of 'evo'
as the commandline uber tool anyway.  ;-)

Also note that the required schema lines changed to these:

from schevo.schema import *
schevo.schema.prep(locals())

So any existing existing schemas will need to be updated with this new
code, as will any existing databases (since schema are now stored in the
database itself).  And the way to update an existing database is...

Well, as soon as we have an 'evo db update DBFILE SCHEMA' commandline
option you'll be able to update existing databases...
