+components (packages), and includes tools that support this scheme.  Packages
+are collections of OCaml modules for which metainformation can be stored.  The
+packages are kept in the filesystem hierarchy, but with strict directory
+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
+compilers that can directly deal with packages.")
