When autotest starts it looks on the path for any file named
autotest/discover.rb. The one in rspec core tells autotest that if it
can find a spec directory that it must be rspec. It already knows that
if it finds config/environment that it must be rails (that's the
assumption made directly by autotest). It then adds words to a list:
rspec, rails, camping, etc - depending on what it learns from the
autotest/discover files and what it discovers.

So in the case of an rspec project, it then looks for a file named
autotest/rspec.rb, which it finds in rspec core. In the case of an
rspec/rails project it looks for a file named autotest/rails_rspec.rb,
which it finds in the rspec_on_rails plugin. These two different files
define two different spec commands. In fact, the one in trunk in core
now generates "ruby bin/spec" if it finds "bin/spec", otherwise it
generates "ruby spec" - that supports using autotest to work on rspec
directly.

That all make sense?
