+     "The Citation Style Language (CSL) is an XML-based language that defines
+the formats of citations and bibliography.  There are currently thousands of
+styles in CSL including the most widely used APA, Chicago, Vancouver, etc.
+The citation-style-language package is aimed to provide another reference
+formatting method for LaTeX that utilizes the CSL styles.  It contains
+a citation processor implemented in pure Lua (@code{citeproc-lua}) which reads
+bibliographic metadata and performs sorting and formatting on both citations
+and bibliography according to the selected CSL style.  A LaTeX package
+(@file{citation-style-language.sty}) is provided to communicate with the
+processor.")
