SyncKolab 0.6.0 - Keeps Mozilla Thunderbird Contacts In Sync

Chew like a cow.
Now, did your tongue go from left to right or from right to left? Is it difficult to reverse the direction? Surely, this must mean something!
Mozilla Thunderbird, a bird after all, has difficulties moving your contacts anywhere — let alone keeping two computers' contacts in sync. Enter SyncKolab, which chews on all your data merrily again and again moving it from left machine to right machine and back again elegantly; yes, elegantly:
›› SyncKolab synchronizes your Mozilla Thunderbird contacts as well as Lightning/Sunbird calendars and tasks across computers using any old IMAP email folder.
