sfk join inputfile.part1 [outputfilebase] [-test]
sfk sel ... +fjoin outputfile

join many input files into one output file. input files.

with join
- filenames must end like .part1, .part001 etc.
- if outputfilebase is omitted, outputfilename is just
  like inputfile, but without the ".part1" extension.

with fjoin
- accepts any input list of input filenames.
- output filename must be given.

options
   -test   does not really join the files, but reads all
           input files, telling the overall md5 checksum.
           join -test is recommended after every "sfk split"
           command, to verify if the splitted files are ok
           and can be rejoined.
   -force  if the output file exists already, overwrite it
           without asking back.
