I installed HTTrack and I am loving it. During the testing phase, I configured
track to download multiple web sites as multiple projects and then I realised
that all the sites can be put in a list and managed as one project.

On exploring the directory structure of HTTrack and the hts-cache, I think
that all these projects can be merged.

My question is this: Is there a way of merging all the projects without
screwing up HTTrack?
