+ <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.
