#               - list prefixes in ~/wp/
#
#       wp prefix
#               - if ~/wp/prefix exists, child shell into it and set WINEPREFIX
#               - otherwise, prompt to create the given prefix and
#                 then do as above if new prefix was created
#               - child shell is bash and you can get out of it via the
#                 usual means (^D, exit)
#               - PS1 is set to reflect the choice of prefix
#
#       NOTE:   the script sets WINEARCH to win32.  Hack around it
#               if you play new games.
