Dirk Eddelbuettel: pkgKitten 0.2.1: Now with roxygen2 support
new release 0.2.1 of pkgKitten hit CRAN earlier today, and has been uploaded to Debian as well. pkgKitten makes it simple to create new R packages via a simple function invocation. A wrapper kitten.r exists in the littler package to make it even easier.
This release builds on the support for tinytest we added in release 0.2.0 by adding more optional support, this time for roxygen2. It also corrects a minor documentation snafu, and updates the CI use.
