For this tutorial, we have the following brief. That is: to take a file that contains many millions of lines of text, each one of them a single column — something that looks like this:

POPLKLMNE
GKITLOPOM
QASSLKOPI
== snip ==

...into multiple text files, each with a fixed number of lines in them, each with — instead of one column per line — several columns, separated with a comma. In other words, something that looks like this:

POPLKLMNE,GKITLOPOM,QASSLKOPI
