Query package server and installed packages and display results. Query is matches case-insensitively against the name and title of known and installed packages. For each matching package, a single line is displayed that provides:

Installation status
- p: package, not installed
- i: installed package; up-to-date with public version
- a: as i, but installed only as dependency
- U: installed package; can be upgraded
- A: installed package; newer than publically available
- l: installed package; not on server
Name@Version
Name@Version(ServerVersion)
Title

Options processed:

installed(true): Only list packages that are locally installed. Contacts the server to compare our local version to the latest available version.
outdated(true): Only list packages that need to be updated. This option implies installed(true).
server((Server|false)): If false, do not contact the server. This implies installed(true). Otherwise, use the given pack server.

Hint: ?- pack_list(''). lists all known packages.

The predicates pack_list/1 and pack_search/1 are synonyms. Both contact the package server at https://www.swi-prolog.org to find available packages. Contacting the server can be avoided using the server(false) option.
