I'm trying to obtain the docs in both html and pdf format for fpc 2.6.2. No problem downloading from the ftp site, but no matter whether I get the .zip, .tar.gz, or tar.gz archive format, on my OS X 10.9 Mac I cannot successfully extract the actual documentation. E.g., with the .zip file, if I unarchive it I just get a .zip.zip file! I've tried several different unarchive utilities, including command-line tar. What could be wrong?
