-# == Synopsis
-#
-# arv-run-pipeline-instance --template pipeline-template-uuid [options] [--] [parameters]
-# arv-run-pipeline-instance --instance pipeline-instance-uuid [options]
-#
-# Satisfy a pipeline template by finding or submitting a mapreduce job
-# for each pipeline component.
-#
-# == Options
-#
-# [--template uuid] Use the specified pipeline template.
-#
-# [--template path] Load the pipeline template from the specified
-# local file.
-#
-# [--instance uuid] Use the specified pipeline instance.
-#
-# [-n, --dry-run] Do not start any new jobs or wait for existing jobs
-# to finish. Just find out whether jobs are finished,
-# queued, or running for each component
-#
-# [--submit] Do not try to satisfy any components. Just
-# create an instance, print its UUID to
-# stdout, and exit.
-#
-# [--no-wait] Make only as much progress as possible without entering
-# a sleep/poll loop.
-#
-# [--no-reuse] Do not reuse existing jobs to satisfy pipeline
-# components. Submit a new job for every component.
-#
-# [--debug] Print extra debugging information on stderr.
-#
-# [--debug-level N] Increase amount of debugging information. Default
-# 1, possible range 0..3.
-#
-# [--status-text path] Print plain text status report to a file or
-# fifo. Default: /dev/stdout
-#
-# [--status-json path] Print JSON status report to a file or
-# fifo. Default: /dev/null
-#
-# [--description] Description for the pipeline instance.
-#
-# == Parameters
-#
-# [param_name=param_value]
-#
-# [param_name param_value] Set (or override) the default value for
-# every parameter with the given name.
-#
-# [component_name::param_name=param_value]
-# [component_name::param_name param_value]
-# [--component_name::param_name=param_value]
-# [--component_name::param_name param_value] Set the value of a
-# parameter for a single
-# component.
