&gt; Adobe has made the file format available on the web<p>Good for them. Nonetheless, my point stands. In many places, it is illegal to reverse-engineer file formats, and in many places it isn&#x27;t illegal but may as well be due to the potential costs of determining that it is legal.<p>(For instance, &quot;The information in this document is furnished for informational use only, is subject to change without notice, and should not be construed as a commitment by Adobe Systems Incorporated. &quot;. What happens if&#x2F;when they pull said document?)<p>(Also: note that them documenting their file format is <i>not</i> the same thing as there being no potential liability for anyone to use said info.)
