Subject: OptionParser questions

I'm a bit confused by the way that OptionParser works.  In
the "Complete example" on


http://www.ruby-doc.org/stdlib/libdoc/optparse/rdoc/classes/OptionParser.html

I see

  opts = OptionParser.new do |opts|
    opts.banner = "Usage: example.rb [options]"
    ...

It looks like the "opts" object is being handed to the block,
as well as being returned as the result of the "new" method.
Is this the case?  Is this a common way of doing things?  Are
there any caveats that must be observed in this situation?
