Thinking about doing some marketing for some of these coins, you can download the whole file and just made some edits and then re-upload to github under your project..Open Source...Some idiots already paid for the head start on it for you already...lol
Considering the changes from base coin are quite straightforward, you can easily do the same without coingen too .. just get litecoin, make some edits, re-upload to github under your project. May be better than scavenging through the trash near coingen output.
The only benefit would be if actually that fool will start promoting the coin for you (i.e. he will do that "hard work"), but as these new coins won't have any start node probably (at least not at time of downloading), you're just sitting on a fork, not knowing where the rest of the network is (if there is any)
