Along about now also seems to be a good place to explain how free software works. Suppose programer A has an itch, so he writes a piece of code that scratches his itch, and is currently makeing 4000 of this itch scratcher a day. His itch has been scratched, but your itch isn't in the same place, so while his solution is similar, he'll have to modify that code in order to scratch your itch. But he is a working man, and to rewrite his code to scratch your itch, he'll have to stop whatever he is doing, which is buying his groceries and making the house payments. Generally he is going to expect that this missed income will be replaced by charging you for the time it takes to do this modification. You are not paying for the code, but the coders time. This makes all the difference in the GPL world. This modified code is also subject to the GPL in that if you pass it on to your brother-in-law, the complete src file kit must be made available to anyone who has a copy of the executable that came from you. There are probably 20+ people on this list who could handle this, (and I'm not one of them by any means,) but they would want a per diem, all expenses paid and in person access to the machine at X dollars, Dinar, Sheckles, whatever the local monetary unit is called, per hour while they are doing this work if as you claim you aren't able to do it. Thats rather harshly stated. But its as often as not, how free (GPL) software works. Too often I have observed that there are folks with plenty of smarts, but because the code "forest" is not familiar, cannot look and see what its doing, and without that, haven't the comprehension to look at the existing code and follow what its doing. And reaching that understanding will get you to easily seeing a variable that needs changed to get it closer to scratching "your" itch. Often referred to as the TANSTAAFL principle. :) -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
