Subject: two questions: one for XML Builder, one for ERB.

1.
 require_gem 'builder'


 builder = Builder::XmlMarkup.new(:target�=>STDOUT, :indent=>2)
 builder.person { |b| b.name("Jim"); b.phone("555-1234") }


 #
 # Prints:
 # <person>
 #   <name>Jim</name>
 #   <phone>555-1234</phone>
 # </person>


The code is clear, but how to understand "builder.person"? A dynamic
method?


2.


require 'erb'
File.open( ARGV[0] ) { |fh|
erb = ERB.new( fh.read )
print erb.result( binding )



}


How to understand "binding"? Where does it defined?

Thanks for any help!
