MMISoftware has released
iCalMaker. It’s a new Mac OS X application designed to quickly create appointment info for use in iCal and other vCal-format-compatible applications.
You can use iCalMaker to import data from the clipboard, tab and comma-delimited text files, Palm Desktop files, and more. You can also use iCalMaker to merge appointments from multiple calendars.
What’s more, iCalMaker can be used to create single or repeating appointments, “request appointments” that are sent through e-mail, and more.
iCalMaker is distributed as shareware. It runs natively in Mac OS X and costs US$25 to register. A demo version is available.
