	Q. What is the difference between the Open Source and Commercial editions? 
	A.   The main difference is licensing. Using the Open Source Edition (under
	 the GPL license) obligates you to share your source code without
	 restrictions with the users of your program. Using the GPL also means you
	 may not demand compensation for or limit subsequent re-use and
	 re-distribution of the source code. 
	 You need the commercial license if you want to avoid these obligations. 
	 In addition, some tools and add-ons will be available exclusively to
	 commercial license holders.

The commercial license is only needed to avoid the GPL obligations or for 
non-Free tools/add-ons.
