The template script contains snippets for best practices and leaves out the commands that

Hola. En mi caso, no he podido resolver los problemas con el Java para usar XLConnect, que en los papeles me parece el mejor.

Hi, I'm documenting a package that makes heavy use of S4 methods at the moment, and I'm having a hard time from keeping the PDF output of Rd from looking really terrible.
