script - Run scripts to create output
=====================================
This element allows one to run some commands to mutate the
input and create some output.
.. note::
Script elements may only specify build dependencies. See
:ref:`the format documentation <format_dependencies>` for more
detail on specifying dependencies.
The default configuration and possible options are as such:
.. literalinclude:: ../../../src/buildstream/plugins/elements/script.yaml
:language: yaml
