+<h2><a name="hints">Hints and Advice</a></h2>
+
+<ul>
+<li>The generated LLVM code will be easier to read if
+you use stdio (e.g., printf) than iostreams (e.g., std::cout).</li>
+
+<li>Unused inline functions and methods are not generated.  Instead 
+of '<tt>class foo { void bar() {}};</tt>',
+try writing '<tt>class foo { void bar(); }; void foo::bar() {}</tt>'.</li>
+
+<li>If you want to try out a file that uses non-standard header files,  you should
+  preprocess it (e.g., with the <tt>-save-temps</tt> or <tt>-E</tt> options to
+  <tt>gcc</tt>) then upload the result.</li>
+
+</ul>
+
+
+<h2><a name="demangle">Demangle C++ names with C++ filt</a></h2>
+
+<p>
+Select this option if you want to run the output LLVM IR through "c++filt", 
+which converts 'mangled' C++ names to their unmangled version. 
+Note that LLVM code produced will not be lexically valid, but it will 
+be easier to understand.
+</p>
+
+<h2><a name="lto">Run link-time optimizer</a></h2>
+
+<p>
+Select this option to run the LLVM link-time optimizer, which is designed to
+optimize across files in your application.  Since the demo page doesn't allow
+you to upload multiple files at once, and does not link in any libraries, we
+configured the demo page optimizer to assume there are no calls 
+coming in from outside the source file, allowing it to optimize more 
+aggressively.</p>
+
+<p>Note that you have to define 'main' in your program for this 
+to make much of a difference.
+</p>
+
+<h2><a name="stats">Show detailed pass statistics</a></h2>
+
+<p>
+Select this option to enable compilation timings and statistics from various
+optimizers.</p>
+
+
+<h2><a name="bcanalyzer">Analyze generated bytecode</a></h2>
+
+<p>
+Select this option to run the <a 
+href="http://llvm.org/cmds/llvm-bcanalyzer.html">llvm-bcanalyzer</a> tool
+on the generated bytecode, which introspects into the format of the .bc file
+itself.  </p>
+
+
+<h2><a name="llvm2cpp">Show C++ API code</a></h2>
+
+<p>
+Select this option to run the <a 
+href="http://llvm.org/cmds/llvm2cpp.html">llvm2cpp</a> tool
+on the generated bytecode, which auto generates the C++ API calls that could
+be used to create the .bc file.
