Usage: vcfconvert.sh [-hilmpv] [-d delimiter] [-c utf-8] [-b identifier] [-o output_file] -f format <file>
  -f Target format (ldif,ldap,csv,gmail,libdlusb,fritzbox,img)
  -b LDAP identifier added to dn:
  -l Generate just a list of DN objects (only works with -b)
  -o Output file (write to stdout by default)
  -d CSV col delimiter
  -h Include header line in CSV output
  -i Convert CSV output to ISO-8859-1 encoding (deprecated, use -c instead)
  -c Character encoding for CSV output
  -n Line endings for CSV output: 'n', 'r' or 'rn'
  -m Only convert cards with an e-mail address
  -p Only convert cards with phone numbers
  -v Verbose output
