	: CPAN module that uses the Rembedded API to provide a thin wrapper around
	: R code evaluation. Forking is used to support multiple interpreters, but
	: data is not shared after the fork, nor is there a sharing mechanism
	: built-in for use after the fork (that is, *besides* loading the
	: necessary data before forking).
