In the past Google Calendar exports were done by first removing all
events of a day and then create new ones. This takes a lot of time for
export and runs into Google Calendar usage limits after some time.
By now content will be compared before removing/creating a single event
one. To be able to do so, all other sync sources and targets have been
removed, so its only possible to export from database to Google Calendar
by this change.
To trigger an export you need to create a trigger file.
run_jobs.pl runs periodically e.g. started by cron and checks if a
trigger file exists and start sync_cms.pl to export the selected events
to the Google Calendar. Trigger files and jobs are configured at
jobs.config. Each job has a source and target file containing the access
data for calcms and the calendar.
Configuration files have been cleaned up. Old Accounts and passwords have
been removed. They hopefully should have been not active for a long time ;-)
