I use a Perl script notice.pl to read entries from a structured text file, to tell mum what she's got on every day. The Perl script constructs an HTML page, which the conkeror browser displays, on workspace 3. A cron job runs the script daily, just after midnight.
I've commented the script, so that all but the most gothic bits should make sense. I've included a sample diary file. You'll probably want to tweak these bits:
This was one of the first scripts I wrote for this project, and I never envisaged making it public, so - go easy on me; I'm a writer, not a coder :-) TIMTOWTDI, remember, and I rarely pick the most elegant or logical. But that's why I love Perl - it makes allowances for me.
I hope it helps; feedback is always welcome.
