Count the FTP transfer log items by date, with options for filtering.

Options:

   -h   Help
   -r   Remote host to match
   -f   File path to match
   -u   User name to match
   -c   Completion status to match, either "c" or "i"

Example to count transfers of the file name `hello.txt`:

    cat /var/log/proftpd/xferlog |
    xferlog-count -f hello.txt

Example to count transfers by a user name `alice`:

    cat /var/log/proftpd/xferlog |
    xferlog-count -u alice

Example to count transfers with a completion status of `c` meaning complete:

    cat /var/log/proftpd/xferlog |
    xferlog-count -c c

This script expects typical xferlog line format:

  * start with a three-field current time, e.g. "Sat Dec 31".
  * contain the remote host, file path, and user name.
  * end with "c" for complete or "i" for incomplete.
