* Get rid of non-compliant <font> elements (how did that get in there?)

Note that you normally do not need to specify the sources involved. The LLVM
Makefile system will infer the source files from the contents of the source

+ <p>The <tt>LOADABLE_MODULE=1</tt> directive can be used in conjunction with
+ <tt>SHARED_LIBRARY=1</tt> to indicate that the resulting shared library should
+ be openable with the <tt>dlopen</tt> function and searchable with the
+ <tt>dlsym</tt> function (or your operating system's equivalents). While this

+ <a href="WritingAnLLVMPass.html#makefile">WritingAnLLVMPass.html</a> document
