For a given art job command, the --config-summary program option can be specified to see configuration information about the job, without executing the job. A summary of the active components of the job, ignoring unused modules or paths, will be printed to the terminal. Three verbosity levels are available:

art --config-summary          ... # Brief summary (implicit)
art --config-summary=brief    ... # Brief summary
art --config-summary=detailed ... # More information, including service names, etc.
art --config-summary=full     ... # Even more information, including module labels and types, etc.

Resolves feature #24526.

Users can now enable configuration description and validation for Source detail/policy classes. This is done by introducing a type alias of the form (e.g.):

class MyPolicyClass {
public:
  struct Config {
    fhicl::Atom<std::string> par1{fhicl::Name("par1")};
    ...
  };
  using Parameters = art::SourceTable<Config>;
  MyPolicyClass(Parameters const&, art::ProductRegistryHelper&, art::SourceHelper&);
};

Resolves feature #24573.
