ssft.sh  is  a  library  of  shell  functions  that  must be sourced from other scripts. If the script is
       executed without arguments it prints an usage message and also supports the  options  --doc,  --help  and
       --version.

       To  get a list of available functions call the script with the --doc argument and to get a description of
       what a given function does call the script with --docFUNCTION_NAME.

       On the typical case the library must be sourced and the SSFT_FRONTEND variable must be set to the desired
       frontend (zenity, dialog or text); if the variable is not set the default frontend is noninteractive.

       To choose the theoretically best looking frontend use the function ssft_choose_frontend as follows:

              . ssft.sh
              [ -n "$SSFT_FRONTEND" ] || SSFT_FRONTEND="$( ssft_choose_frontend )"
