+\section{Snow Package Manager}
+
+Beyond the distributed modules, Chibi comes with a package manager
+based on \hyperlink["http://trac.sacrideo.us/wg/wiki/Snow"]{Snow2}
+which can be used to share R7RS libraries.  Packages are distributed
+as tar gzipped files called "snowballs," and may contain multiple
+libraries.  The program is installed as \scheme{snow-chibi} and takes
+the following subcommands:
+
