Namespaces
	osvr
	The main namespace for all C++ elements of the framework, internal and external.

	osvr::util
	The Util library: Functionality not necessarily coupled to any particular core library, serving more as a common base layer behind all systems.

Functions
boost::optional< std::string >	osvr::util::getEnvironmentVariable (std::string const &var)
	Gets an environment variable's value. On systems that don't distinguish between having a variable defined and having it non-empty (like Windows), empty will imply not defined and thus an empty boost::optional return value.
