+# RDoc::TestCase is an abstract TestCase to provide common setup and teardown
+# across all RDoc tests.  The test case uses minitest, so all the assertions
+# of minitest may be used.
+#
+# The testcase provides the following:
+#
+# * A reset code-object tree
+# * A reset markup preprocessor (RDoc::Markup::PreProcess)
+# * The <code>@RM</code> alias of RDoc::Markup (for less typing)
+# * <code>@pwd</code> containing the current working directory
+# * FileUtils, pp, Tempfile, Dir.tmpdir and StringIO
