Building package - tab delimited example data issue

The passage you cite from the manual could do with a
rephrasing, although it probably isn't technically incorrect. As it
stands, it reminds me a bit of the old Monty Python sketch:

"Our *three* weapons are fear, surprise, and ruthless efficiency...and
an almost fanatical devotion to the Pope.... Our *four*...no...
*Amongst* our weapons.... Amongst our weaponry...are such elements as
fear, surprise.... I'll come in again"

(There really are 3 data TYPES, but 4 FORMATS and, er, diverse
EXTENSIONS)
