When reading, the values are read from all configuration sources.
The options --global and --user can be used to tell the command to read
from only one of the sources. If a configuration key is available from

the user configuration file and lastly the global configuration file.
When writing, the new values are written to the user configuration by default.
The options --global and --user can be used to tell the command to write
to only one of the sources.
When removing keys, the values are removed from all sources.
The options --global and --user can be used to restrict removal to one of
the sources.
To assign a value to a key:
$ jolt config jolt.default all # Change name of the default task
To list existing keys:
$ jolt config -l # List all existing keys
$ jolt config -l -g # List keys in the global config file
$ jolt config jolt.colors # Display the value of a key.

"""
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.
