 structured and the node types are context-independent. The layer makes
 it possible to transparently attach source-code comments and user
 annotations to nodes of the tree. Using the abstract layer makes

-      {@link erl_syntax:class_qualifier/2. class-qualifier patterns}.</li>
-  <li>Added support for parameterized modules.</li>
-  <li>{@link igor. Igor} is officially included.</li>
-  <li>Quick-parse functionality added to {@link epp_dodger}.</li>

-<p>News in 1.2:
-<ul>
-  <li>HTML Documentation (generated with EDoc).</li>
-  <li>A few bug fixes and some minor interface changes (sorry for any
-    inconvenience).</li>

-<p>News in 1.1:
-<ul>
-  <li>Module {@link erl_tidy}: check or tidy either a single module, or a
-    whole directory tree recursively. Rewrites and reformats the code
-    without losing comments or expanding macros. Safe mode allows
-    generating reports without modifying files.</li>
-  <li>Module {@link erl_syntax_lib}: contains support functions for easier
-    analysis of the source code structure.</li>
-  <li>Module {@link epp_dodger}: Bypasses the Erlang preprocessor - avoids
-    macro expansion, file inclusion, conditional compilation, etc.
-    Allows you to find/modify particular definitions/applications of
-    macros, and other things previously not possible.</li>
-</ul>

+Also try the {@link erl_tidy} module, as follows:
+```erl_tidy:dir("any-erlang-source-dir", [test, old_guard_tests]).'''
+(the `test' option assures that no files are modified).
