WP-34S PDF Manual Vers 3.3 Availability?

[BarryMead]

The "Steam" DRM company has applications for Linux, Windows, Mac, and other platforms.
They have DRM protected PDF documents (Strategy Guides) for video games that they sell through their store, and protect with their DRM.

People trust "Steam" and it is likely that they will be around for a long time. When you buy a game or strategy guide from Steam, it is always
available both online and offline and their DRM tool/offline viewer works on all platforms.

Perhaps that would be an option.
