<summary>Performs operations on modules - compiling, running tests, packaging/registering, etc.</summary>
<description>
Performs operations on modules - compiling, running tests, packaging/registering, etc.
You can use this by starting a command with the module name.
Note that flags appear *after* all actions.

The standard lifecycle phases are:
* clean: removes all dependencies that are not required by other installed modules and
their resources. Dependencies required by other modules will also be removed if the -DClean.Force=1 flag is specified.
* reload: pulls module source code into the namespace from disk. Does not compile.
* validate: ensures that module resource processor attributes are valid, and that the
resources exported to the filesystem (and possible to source control) are consistent
with what is in the database.
* compile: compiles all resources within the module.
* activate: performs post-compilation installation/configuration steps.
* makedeployed: deploys resources within the module for which deployment is enabled.
* document: regenerates the API documentation for the module
* test: runs any unit tests associated with the module, in the current namespace.
* package: exports the module's resources and bundles them into a module artifact (.tgz file).
* verify: installs that artifact in a separate namespace, then runs integration tests (if any).
* register: saves that artifact into the current namespace's module cache.
This is accessible to other instances configured to look at the current namespace as a
module repository.
* publish: saves that artifact to the repository for which deployment is enabled.
Currently, there may only be one of these per namespace.
* applyupdatesteps: run any update steps for the module to become updated to the latest available version.
Can also specify desired version to update to.
