  # Displays context help. You can pass the content of the help message as the
  # first parameter or using template code inside a block passed to this
  # method. *Note*: the block is ignored if <tt>content</tt> is not
  # <tt>nil</tt>
  #
  # The method returns the text generated, so you can also use it inside a
  #  <%= ... %>
  #
  # Follow some examples ...
  #
  # Passing the text as argument:
  #
  #  <% help 'This your help message' %>
  #
  # Using a block:
  #
  #  <% help do %>
  #    This is the help message to be displayed. It can contain any HTML you
  #    want: <strong>bold</strong>, <em>italic</em>. It can also contain calls
  #    to any Rails helper, like <%= link_to 'home', :controller => 'home' %>.
  #  <% end %>
  #
  # You can also pass an optional argument to force the use of textile in your
  # help message:
  #
  #  <% help nil, :textile do %>
  #    You can also use *textile*!
  #  <% end %>
  #
  # or, using the return of the method:
  #
  #  <%= help 'this is your help message' %>
  #
  # Formally, the <tt>type</tt> argument can be <tt>:html</tt> (i.e. no
  # conversion of the input) or <tt>:textile</tt> (converts the message, in
  # textile, into HTML). It defaults to <tt>:html</tt>.
