 ** NAME
 **   edit_hc - edits the AFD host configuration file
 **
 ** SYNOPSIS
 **   edit_hc [options]
 **            --version
 **            -w <AFD working directory>
 **            -f <font name>
 **            -h <host alias>
 **
 ** DESCRIPTION
 **   This dialog allows the user to change the following parameters
 **   for a given hostname:
 **       - Real Hostaname/IP Number
 **       - Transfer timeout
 **       - Retry interval
 **       - Maximum errors
 **       - Successful retries
 **       - Transfer rate limit
 **       - Max. parallel transfers
 **       - Transfer Blocksize
 **       - File size offset
 **       - Number of transfers that may not burst
 **       - Proxy name
 **   additionally some protocol specific options can be set:
 **       - FTP active/passive mode
 **       - set FTP idle time
 **       - send STAT to keep control connection alive (FTP)
 **       - FTP fast rename
 **       - FTP fast cd
 **
 **   In the list widget "Alias Hostname" the user can change the order
 **   of the host names in the afd_ctrl dialog by using drag & drop.
