SYNOPSIS.

SUMMARY.
If you only type, /unload a File Browser will appear, and you can browse to the file that you want to unload from savIRC.
The type defaults to Functions but the available choices are:
Functions
Events
Popups
Variables
So after you loaded the file MiscFunctions.tcl you decide you want to unload it. You would do this.
/unload MiscFunctions.tcl functions
