"""
Build task artifact.
TASK is the name of the task to execute. It is optionally followed by a colon and
parameter value assignments. Assignments are separated by commas. Example:
taskname:param1=value1,param2=value2
Default parameter values can be overridden for any task in the dependency tree
with --default. DEFAULT is a qualified task name, just like TASK, but parameter
assignments change default values.
By default, a task is executed locally and the resulting artifact is stored
in the local artifact cache. If an artifact is already available in the cache,
no execution takes place. Artifacts are identified with a hash digest,
constructed from hashing task attributes.
When remote cache providers are configured, artifacts may be downloaded from and/or
uploaded to the remote cache as execution progresses. Several options exist to control
the behavior, such as --local which disables all remote caches.
Distributed task execution is enabled by passing the --network option. Tasks are then
distributed to and executed by a pool of workers, if one has been configured.
Rebuilds can be forced with either --force or --salt. --force rebuilds the requested
task, but not its dependencies. --salt affects the entire dependency tree. Both add
an extra attribute to the task hash calculation in order to taint the identity and
induce a cache miss. In both cases, existing intermediate files in build directories
are removed before execution starts.
