Have fun! Thanks for your efforts! Quick question, the dependency on zlib seems to come from using adler32() for checksum comparison. In the code you seem to compare the total amount of data anyway, so I guess the checksum seems to be there to get some early notification about potential mismatch. The potential error will be discovered using the full-data-comparison later on anyway. I'm not sure if that's the way the code works, but if so then it should be easy to reduce the number of dependencies by simply dropping the checksum code. Does that make sense to you?
