What does this tool do?

ICS files exported from the scheduler export tool in STiNE do not conform to the official iCalendar spec (RFC 5545).
Many calendar application therefore have problems opening them.

This tool…

…removes NULL bytes
…converts file encoding from ISO8859-1 to UTF8
…removes empty lines and wraps long lines
…ensures line endings are CRLF
…combines all files into one
…detects recurring events and merges them using RRULEs
