<%
  def menu_item(current_filename, page_filename, page_title)
     if current_filename == page_filename
        page_title
     else
        "<a href=\"#{page_filename}\" title=\"#{page_title}\">#{page_title}</a>"
     end
  end

  fname = File.basename ENV['SCRIPT_FILENAME']
%>
<%= menu_item(fname, "index.rhtml", "Home") %> &nbsp;&nbsp;::&nbsp;&nbsp;
<%= menu_item(fname, "contact.rhtml", "Contact" %> &nbsp;&nbsp;::&nbsp;&nbsp;

You can continue with storing the menu in an array, i.e.

<%
def make_menu(menu, separator)
   fname = File.basename ENV['SCRIPT_FILENAME']
   menu.map {|page_file, page_title| menu_item(fname, page_file,
page_title)}.join(separator)
end

MENU = [
  ['index.rhtml, 'Home'],
  ['contact.rhtml', 'Contact']
]
%>

<%= make_menu(MENU, " &nbsp;&nbsp;::&nbsp;&nbsp; ") %>
