I've just committed code that allows R to be built with support for dynamic help pages using \Sexpr in Rd files. Define USE_NEW_HELP and the R function tools:::.convertRdfiles will be used instead of the Perl RdConv script, supporting \Sexpr and using the new R converters. Currently only text help has the macros evaluated when the user asks for help; the others are rendered at install time. Hopefully HTML rendering will also be in place before the 2.10.x release....
