Hello, Statalist!

I can't figure out how to get around -bootstrap-'s inability to apply
weights.  I'd like to do something like the following (assuming it's
correct, in principle):

bootstrap me_se=r(sd): sum me [fweight=number]
bootstrap me_se=e(b): reg me [fweight=number]

where 'me' is a statistic for which I am trying to get a standard error.

Data look something like below, with 'me' being the statistic and
'number' being the number of times that value is repeated in the
population.  The actual sum of 'number' is over 100,000,000.

me                                number
