+The RSP markup language makes any text-based document come alive. RSP provides a
+powerful markup for controlling the content and output of LaTeX, HTML, Markdown,
+AsciiDoc, Sweave and knitr documents (and more), e.g. 'Today's date is
+<%=Sys.Date()%>'. Contrary to many other literate programming languages, with
+RSP it is straightforward to loop over mixtures of code and text sections, e.g.
+in month-by-month summaries. RSP has also several preprocessing directives for
+incorporating static and dynamic contents of external files (local or online)
+among other things. Functions rstring() and rcat() make it easy to process RSP
+strings, rsource() sources an RSP file as it was an R script, while rfile()
+compiles it (even online) into its final output format, e.g.
+rfile('report.tex.rsp') generates 'report.pdf' and rfile('report.md.rsp')
+generates 'report.html'. RSP is ideal for self-contained scientific reports and
+R package vignettes. It's easy to use - if you know how to write an R script,
+you'll be up and running within minutes.
