The taskcluster CLI client installed as taskcluster provides a collection of command line utilities ranging from simple utilities exposing all APIs to more special case task like signing-in, admin-scripts or creating of loaners.

For a list of all commands run taskcluster help, detailed information about each command is available with taskcluster help <command>. Some commands may even specify additional help for sub-commands using taskcluster <command> help <subcommand>, refer to the individual commands help text for details.

A command is just an implementation of the CommandProvider interface, which is registered in func init() {...} using extpoints.Register(name, implememtation). Thus, commands are registered as an import side-effect.

Using the go-import-subtree command all sub-packages will be imported in the top-level main package. Hence, commands can be organized in sub-packages as appropriate, just run go generate to ensure they are imported in the main package.
