> Beam's programming guide provides a tutorial-like structure to introduce the user to the main concepts.
> Due to flaws of the snippets the copied code needs altering to work.
> Some of the problems:
> * Section "Creating the pipeline"
> ** {{import apache_beam as beam}} statement is missing from the beginning
> ** The command line arguments are not parsed
> * Section "Creating a PCollection from in-memory data"
> ** {{pipeline_options}} variable is undefined
> ** {{my_options}} variable is undefined
> * Section "ParDo": 
> ** It is not explained how to define {{words}} variable
> * Section "Advanced combinations using CombineFn" and "Combining a PCollection into a single value" has the same code snippet
> * Section "Combining values in a key-grouped collection":
> ** It is not explained how to define {{player_accuracies}}
> * Section "Using Flatten and Partition"
> ** The code snippet contains unnecessary markers ({{[START model_multiple_pcollections_tuple]}})
> * Section "partition":
> ** {{students}} variable is undefined
> This list might not be complete.
