I would like to submit to the RAA a ruby Rijndael cryptography class. !. How do I post it to a publicly available location like ftp.ruby-lang.org since I don't maintain my own site. And, what is required for a page like www.ruby-lang.org uses. 2. I developed this on MacOSX beta, is there some mechanism to incorparate changes needed by other operating systems, i.e. Microsoft, other than a feedback through comments by users or each user on his own to make it work on his system? I am deeply grateful to the Darwin implementers of Ruby. 3. Is there a way in extconf.rb to add dependencies for c files with their header files? Thanks, Donald Huebschman
