Jaevner is a tool for exporting data from a Lotus Notes calendar and importing it into a Google Calendar. Yes, there are other tools that are available that do this. Yes, it can be done using the export and import features of Lotus Notes and Google Calendar. But I have created this anyway.
It is a simple one-way export/import. Any changes you make on the Google Calendar side will be overwritten the next time the tool is run.
At the core it has two parts: A piece of LotusScript code that runs in Lotus Notes, exporting your calendar data as a CSV file. It also starts the second part of the tool, which is a console application that reads the exported calendar data and inserts it into a Google Calendar of your choice.
