+The @script@ and @script_version@ attributes of a Job allow you to confirm the code that was used to run the job. Specifically, @script@ refers to a file in the @/crunch_scripts@ directory in the tree indicated by the commit hash @script_version@.

+Example:
+
+<pre>
+cd
+git clone git://github.com/clinicalfuture/arvados.git
+cd arvados
+git checkout $the_version
