Usage: ftar [OPTION] ... SOURCE

   -1                   Use only first tar file matching class name.
   -c class[class]      Define classes (space separated).
   -d                   Delete all files in target before extracting.
   -D                   Create debug output.
   -h                   Show summary of options.
   -r                   Recursively remove files in target before extracting.
   -s source_dir        Look for source files relative to source_dir.
   -t target_dir        Extract files relativ to target_dir.
   -v                   Be verbose. Not yet used.
