<p>Several of the LLVM libraries define static <tt>cl::opt</tt> instances that
will automatically be included in any program that links with that library.
This is a feature. However, sometimes it is necessary to know the value of the
command line option outside of the library. In these cases the library does or
should provide an external storage location that is accessible to users of the
library. Examples of this include the <tt>llvm::DebugFlag</tt> exported by the
<tt>lib/Support/Debug.cpp</tt> file and the <tt>llvm::TimePassesIsEnabled</tt>
flag exported by the <tt>lib/VMCore/Pass.cpp</tt> file.</p>
