I see two ways of doing this.

• A Test::Builder method which clears the formatters and adds a new one. change_formatter()?
• Change Test::Builder::Module->import so it understands a "formatter" option.

The former is the most flexible, and easier than the user having to clear and set the formatter in two steps. The latter allows use Test::More formatter => TB2::Formatter::POSIX but it will work for any module derived from Test::Builder::Module.

Implement both.
