   Usage: $0 [option] [bee-file]...

   Convert old bee files into new be0 format. By the
   way the script also removes white space clutter at
   EOL. And when inside a git repo, renaming is done
   with 'git mv'.

   options:
      -h    show this help and exit
      -n X  set new version (e.g. 0.8.15)
      -i    increase build number
