boot vs. bootstrap

Dear R People:

There is a library boot and another one bootstrap.

When is it preferable to use one or the other, please?

In particular, I was wondering about the function boot in the boot
library and the function bootstrap in the bootstrap library.

Those are the main bootstrap functions.

R Version 1.8.1 for Windows.

Thank you for your help in advance!

Sincerely,
Erin Hodgess
