Before I re-invent something I would like to ask if there exists some code
that can be used for create the HTML code for a calendar which I then can
include on a web page.
The module in the standard library can create a calendar but I would like
display my schedule.
My idea is that it would read a simple text file and then create a weekly
calendar view (and/or a monthly) with my schedule.
Does some the code for this exist? (the ones I found all created calendars
but doesn't seem to include any schedule)
Here's most of a monthly calendar CGI script I wrote a couple of years
ago. Modify it to your needs.
