The ?bugs help pages tells us:

WINE   character, path to ‘wine’ binary file, it is tried hard to get 
the information automatically if not given.

WINEPATH    character, path to ‘winepath’ binary file, it is tried hard 
to get the information automatically if not given.


We said "tried hard [...] if not given", if this leads to 
misunderstandings, what wording would you prefer?
