What is the meaning of a “commercial” license?
1, “Standard Edition - is free for download and covered by GNU GPL license (except some components which are distributed under Free License).”
2, "If I use a piece of software that has been obtained under the GNU GPL, am I allowed to modify the original code into a new program, then distribute and sell that new program commercially?
You are allowed to sell copies of the modified program commercially, but only under the terms of the GNU GPL. Thus, for instance, you must make the source code available to the users of the program as described in the GPL, and they must be allowed to redistribute and modify it as described in the GPL.
These requirements are the condition for including the GPL-covered code you received in a program of your own."
1, 2 times the item used in judging the possible commercial site under GPL license, I think is correct?
Please answer me.
