Excellent stuff. Does exactly what I wanted to do, and with a sane interface too.
I think the documentation could do with a bit of cross reference though; for instance, when mentioning that a Net::Google::Calendar::Entry object is expected or emitted, a link to the appropriate documentation would be nice. (Yes, it's easy to go find it yourself, but easier still if there's a clickable link :) )
First post! I'm not aware of any other module on CPAN to interact with a Google calendar. Nonetheless, this is a good module, and is recommended.
The only downside is that I found the documentation a bit confusing and lacking. For example, the "::Event" documentation does not show how to set up a date for an event. But the documentation is still complete and you can figure it out eventually.
