The `taskgraph` package generates TaskCluster task graphs based on collections of task "kinds". Initially, there is only one kind, the "legacy" kind, which reads the YAML files from `testing/taskcluster/tasks` to generate the task graph. Try syntax is implemented by filtering the tasks in the taskgraph after it has been created, then extending the result to include any prerequisite tasks. A collection of `mach taskgraph` subcommands are provided for developers to extend or debug the task-graph generation process.
