Does a FK constraint create an index?

(SQL Server 2000, SP3a)
Hello all!
I was wondering if a foreign key constraint will create an index like a primary key
constraint?
Thanks!

TABLE entry in BOL wasn't wholly specific on whether an index was created in the PK
context (though, it alludes to it later), and I thought maybe the FK description was
potentially similarly vague.
Thanks again!
