This is an excellent article.

It can be downloaded in PDF to read or print separately.

Those with difficulty following line to line will likely do best with the online layout that is only 88 characters wide. The PDF is 120 characters wide and much more difficult to follow line to line.

It is worth printing a copy so those who do not understand PCS can read it and get a clue.

It would be great if someone could adapt "Spoon Theory" to PCS.

GREAT FIND!
