Outputs a space-separated Target ActsOn Origin Condition tuple for each

resolution in the graph. When -dot flag given, outputs nodes and edges

in graphviz directed graph format.

Calculates the source-sharing requirements in reverse starting at the

-rtrace projects or metadata files that inherited source-sharing and

working back to the targets where the source-sharing requirmements

originate.

If one or more '-c condition' conditions are given, outputs the

resolution for the union of the conditions. Otherwise, outputs the

resolution for all conditions.

Outputs a space-separated pair where the first field is an originating

target with one or more restricted conditions and where the second

field is a colon-separated list of the restricted conditions.

In plain text mode, when '-label_conditions' is requested, the Target

and Origin have colon-separated license conditions appended:

i.e. target:condition1:condition2 etc.

Outputs a count of the originating targets, and if the count is zero,

outputs a warning to check the -rtrace projects and/or filenames.
