Let me make it clear
a channel declares a new file is available:

NewFile XYZ ( /msg LuckyCharms xdcc send #639 )

Normally I copy the command "/msg LuckyCharms xdcc send #639" and paste it in the channel.
If I want to get the file using secure SSL xdcc then i add a 's' to 'send': "/msg LuckyCharms xdcc ssend #639".

Sometime I forget to add the 'S' and the file download is not secure. I want a script to change 'send' to 'ssend' to automate this.
