I download an enormous site starting httrack from a script 
with no action options, so I think it defaults to the 
mirror action.

I apply download time limitation.

Should I start httrack with the -i option if the previous 
download was stopped broken because of the download time 
limitation, or is httrack 'clever enough' to continue the 
incomplete download, even if it is started with 
the 'mirror' action option the next time?
