The following items relating to MacClade version 3.05 are contained on this ftp site: macclade.305.update.package.hqx: this contains an updater that allows one to convert MacClade versions 3.0-3.04 into version 3.05. This contains both a program updater, as well as the latest versions of the Help file, some Example files, a MacClade Font File, and the Supplement to the Book. macclade.305.demo.hqx: this contains a demonstration version of MacClade 3.05. It is like the real thing, except that it cannot save or print, and is limited to small matrices. Both of these files are binhexed. If your software for downloading these files do not automatically de-binhex them, you will need a program that can de-binhex them. (FTP programs like Fetch and gopher programs like Turbogopher automatically de-binhex; utility programs like Compact Pro or Stuffit can de-binhex as well.) These files are self-extracting archives. Starting them up and choosing Extract will cause them to automatically be extracted into their usable format.
