There wasnt any documentation for the merged mining it was used from namecoin.. but the other stuff like reciever file stuff is nicely documented by utb.
Ok, fair enough. But your update development process is still open source and visible. The value of what you're doing is in the progress and effort, as well as the end product. The code is available for anyone else to potentially build upon - devcoin, bitcoin, namecoin, i0coin etc.
But if, say, weisoq - a relative tech ignoramus here - was to work through a lazy idiot's guide to pre-existing cloning that would not warrant my inclusion as an open source developer. Instead it means I'm able to read and follow instructions. If I was able to translate all of your efforts into a simple copy/paste howto, it still doesn't make me an open source developer. It means I can read and write, and that's what devtome is for.
If icoin has incorporated newer functionality and features that's great, and would amount to something different. But I haven't been able to find any further information on glaricoin.
