## 4.9 Other means to synchronization

One correspondent thinks that perhaps the news distribution mechanism could be pressed into service for this job. I could have started from C-news, say, instead of from scratch, and have progressively bent C-news to behave like I wanted.

My feeling is that the route was shorter as I did it, from scratch, that it would have been from C-news. Of course, I could have removed the heavy administrative details of C-news: the history and `expire`, the daemons, the `cron` entries, etc., then added the interactive features and specialized behaviors, but all this clean up would certainly have took energies. Right now, non counting the subsidiary scripts and shar/unshar sources, the heart of the result is a single (1200 lines) script written in Perl, which I find fairly more smaller and maintainable than a patched C-news distribution would have been.
