Usage:
   run-digest-client -h[elp]
   run-digest-client [<find-arguments>] <other-arguments>
or
   java MobyDigest -h[elp]
   java MobyDigest [<find-arguments>] <other-arguments>

where <find-arguments> specify what Moby registry to connect to (or
      what cache to use instead):

   -cachedir <dir>
      a directory where to cache information from a Moby registry;
      depending on -e and -uri there will be a subdirectory in <dir>
      used; if such subdirectory already exists its contents is used
      instead fetching data from the Moby registry; if it does not
      exist it is created and filled with date fetched from the Moby
      registry

   -e <URL>
      <URL> ia an endpoint of a Moby registry
   -uri <namespace>
      <namespace> is a URI defining Moby registry's namespace
 or
   -registry <registry-synonym>
      <registry-synonym> is a convenient way to specify a known registry;
      the list of known registries can be obtained by the -lr option
      from the MobyCmdLineClient (run-cmdline-client -lr)

where <other-arguments> are:
   -t  ... print all service types
   -s  ... print all service instances
   -d  ... print all data types
   -n  ... print all namespaces

   -details  ... print the above with all details
                 (by default only names are printed)

   -summary  ... print summary of the above:
                 - for sevices it is a TAB delimited list of
                   1) number of primary inputs
                   2) number of secondary inputs
                   3) number of outputs
                   4) true/false - is there a collection in inputs?
                   5) true/false - is there a collection in outputs?

   -v[erbose]  ... verbose

[Note: You can also use -argsfile <filename> to read arguments from a
file. See details in src/Clients/help/argsfile.example.]
