  10 bin_library_info.sh is a tool that create a unique filename for a binary tar file that
  11 contain the build of the given source tarfile. the unicity is based on the source tarfile which contains
  12 a md5 already and the calculated sha1 of config_host_.mk and of the tree object associated with the top_level_module
  13 in git.
  14
  15 syntax: bin_library_info.sh -m|--module <top_level_module> -l|--location <TARFILE_LOCATION> -s|--srcdir <SRCDIR> -b <BUILDDIR> -r|--tarfile <LIBRARY_TARFILE> [ -m|--mode verify|name ]
  16
  17 the default mode is 'name' which just print the assocaited binary tarfile name.
  18 in 'verify' mode the programe print the name if the assocaited binary tarfile exist
  19 and print nothing and return an error code if the file does not exist
  20
  21 Note: --location --builddir and --srcdir are optional if they are already in the env in the form of TARFILE_LOCATION and BUILDDIR SRCDIR respectively
