following the currently available list of generators

Generators
  NSIS                        = Null Soft Installer
  STGZ                        = Self extracting Tar GZip compression
  TBZ2                        = Tar BZip2 compression
  TGZ                         = Tar GZip compression
  TZ                          = Tar Compress compression
  ZIP                         = ZIP file format

there should not only be 7Z added, but S7Z and SZIP too. 

The main question is how to specifiy the generator interface in a 
consistent way to be open for further extensions - currently there is a 
mixture of tools, archive types, compression and output formats.
