Support METHOD:CANCEL and UID-based merging?

[vpanteleev-sym]

Hi there,

I've been looking for a tool which would allow me to sort out my mess of a calendar. Thunderbird failed me, so while looking for something more explicit I ran into this tool.

Please correct me if I'm wrong, but looking at the code, it doesn't look like this handles cancellations (METHOD:CANCEL) right now. So, if I were to export all text/calendar attachments from my mailbox, and merge them with this tool, I would still get a calendar file with events that have been long canceled.

I think a more complete merging algorithm would need to do the following:

• Sort the files by generation time
• Apply them in order, minding the METHOD and updates (UID matching a previously-seen event)
• Output the resulting calendar

Hope this helps.
