+# An ERb wrapper that allows nesting of one ERb template inside another.
+#
+# This TemplatePage operates similarly to RDoc 1.x's TemplatePage, but uses
+# ERb instead of a custom template language.
+#
+# Converting from a RDoc 1.x template to an RDoc 2.x template is fairly easy.

+# * %blah% becomes <%= values["blah"] %>
+# * !INCLUDE! becomes <%= template_include %>
+# * HREF:aref:name becomes <%= href values["aref"], values["name"] %>
+# * IF:blah becomes <% if values["blah"] then %>
+# * IFNOT:blah becomes <% unless values["blah"] then %>
+# * ENDIF:blah becomes <% end %>
+# * START:blah becomes <% values["blah"].each do |blah| %>
+# * END:blah becomes <% end %>
+#
+# To make nested loops easier to convert, start by converting START statements
+# to:
+#
+#   <% values["blah"].each do |blah| $stderr.puts blah.keys %>
+#
+# So you can see what is being used inside which loop.
