structure.  The library contains functions to look the directory up that
stores a package, to query metainformation about a package, and to retrieve
dependency information about multiple packages.  There is also a tool that
allows the user to enter queries on the command-line.  In order to simplify
compilation and linkage, there are new frontends of the various OCaml
