2009-12-29 Romain Francois <francoisromain at free.fr>
+ * src/Rcpp_RObject.{h,cpp}: new namespace Rcpp and new class
+ Rcpp::RObject to replace RcppSexp with the same functionality.
+
+ * src/Rcpp_XPtr.h: replaces RcppXPtr.h and the class is now
+ Rcpp::XPtr<> and extends Rcpp::RObject
+
+ * inst/examples/RcppInline/external_pointer.r: use the new namespace
+
+ * inst/examples/RcppInline/RcppInlineWithLibsExamples.r: idem
+
+ * inst/examples/RcppInline/RcppSexpTests.r: idem
+
+ * DESCRIPTION: marked as version 0.7.0.5
+
+ * inst/doc/*: fake (empty) vignette and unit test trigger
+
+ * inst/unitTests/*: prepare the space for unit tests
+
+ * tests/doRUnit.R : added the usual RUnit tests trigger
+
+2009-12-29 Romain Francois <francoisromain at free.fr>
+
* src/RcppXPtr.h: now RcppXPtr extends RcppSexp and RcppSexp manages
garbarge collection, attributes, etc ...
