Oic, apparently HTTrack is the command-line version and WebHTTrack is the GUI
(WinHTTrack, on Windblow$). 

^^ Although, I'm having trouble understanding how, in the world, HTTrack &
WebHTTack are different problems w/o shared dependencies, or anything, meh. 

Anywho, installed WebHTTack & it's difficult to see anything with such
outdated information on the web site (& elsewhere); WebHTTrack.desktop menu
icon says: "Exec=webhttrack" and launching it opens up Firefox (default
browser) in which HTTrack is loaded... 

Not sure if that helps @all. xD
