-# Some custom command to run during setup. The command is not essential for this
-# workflow. It is used here as an example. Each command will spawn a child
-# process. Typically, these commands will include steps to install non-Python
-# packages. For instance, to install a C++-based library libjpeg62 the following
-# two commands will have to be added:
-#
-#     ['apt-get', 'update'],
-#     ['apt-get', '--assume-yes', 'install', 'libjpeg62'],
-#
-# First, note that there is no need to use the sudo command because the setup
-# script runs with appropriate access.
-# Second, if apt-get tool is used then the first command needs to be 'apt-get
-# update' so the tool refreshes itself and initializes links to download
-# repositories.  Without this initial step the other apt-get install commands
-# will fail with package not found errors. Note also --assume-yes option which
-# shortcuts the interactive confirmation.
-#
-# Note that in this example custom commands will run after installing required
-# packages. If you have a PyPI package that depends on one of the custom
-# commands, move installation of the dependent package to the list of custom
-# commands, e.g.:
-#
-#     ['pip', 'install', 'my_package'],
-#
-# TODO(https://github.com/apache/beam/issues/18568): Output from the custom
-# commands are missing from the logs. The output of custom commands (including
-# failures) will be logged in the worker-startup log.
