are collections of OCaml modules for which metainformation can be stored.  The
packages are kept in the file system 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.")
