-# = ERB -- Ruby Templating
-#
-# == Introduction
-#
-# ERB provides an easy to use but powerful templating system for Ruby.  Using
-# ERB, actual Ruby code can be added to any plain text document for the
-# purposes of generating document information details and/or flow control.
-#
-# A very simple example is this:
-# 
-#   require 'erb'
-#
-#   x = 42
-#   template = ERB.new <<-EOF
-#     The value of x is: <%= x %>
-#   EOF
-#   puts template.result(binding)
-#
-# <em>Prints:</em> The value of x is: 42
-#
-# More complex examples are given below.
-#
-#
-# == Recognized Tags
-#
-# ERB recognizes certain tags in the provided template and converts them based
-# on the rules below:
-#
-#   <% Ruby code -- inline with output %>
-#   <%= Ruby expression -- replace with result %>
-#   <%# comment -- ignored -- useful in testing %>
-#   % a line of Ruby code -- treated as <% line %> (optional -- see ERB.new)
-#   %% replaced with % if first thing on a line and % processing is used
-#   <%% or %%> -- replace with <% or %> respectively
-#
-# All other text is passed through ERB filtering unchanged.
-#
-#
-# == Options
-#
-# There are several settings you can change when you use ERB:
-# * the nature of the tags that are recognized;
-# * the value of <tt>$SAFE</tt> under which the template is run;
-# * the binding used to resolve local variables in the template.
-#
-# See the ERB.new and ERB#result methods for more detail.
-#
-# == Character encodings
-#
-# ERB (or ruby code generated by ERB) returns a string in the same
-# character encoding as the input string.  When the input string has
-# a magic comment, however, it returns a string in the encoding specified
-# by the magic comment.
-#
-#   # -*- coding: UTF-8 -*-
-#   require 'erb'
-#
-#   template = ERB.new <<EOF
-#   <%#-*- coding: Big5 -*-%>
-#     \_\_ENCODING\_\_ is <%= \_\_ENCODING\_\_ %>.
-#   EOF
-#   puts template.result
-#
-# <em>Prints:</em> \_\_ENCODING\_\_ is Big5.
-#
-#
-# == Examples
-#
-# === Plain Text
-#
-# ERB is useful for any generic templating situation.  Note that in this example, we use the
-# convenient "% at start of line" tag, and we quote the template literally with
-# <tt>%q{...}</tt> to avoid trouble with the backslash.
-#
-#   require "erb"
-#   
-#   # Create template.
