Hi, William,

I'm putting this patch in, but I'm afraid you lose some functionality
along with it.  In particular, with twill 0.8.4, I started using the
'entry_point' option of setuptools.setup to specify 'twill-sh'.  This
patch to use distutils will fail to upgrade twill-sh in your current
installation, I think.

I switched to the 'entry_point' method in the hopes that this will work
better under Windows than the old 'scripts' mechanism did.  It may well
not work out that way -- I already have another e-mail from someone who
had some problems getting 'twill-sh' to work under 0.8.4 ;).  If I get
enough complaints, I'll switch back to using 'scripts'.

cheers,
