   it requires read access to the data directory.
   You can specify the data directory on the command line, or use
   the environment variable <TT

>.  This utility supports the options
   <TT
CLASS="OPTION"
>-V</TT

CLASS="OPTION"
>--version</TT
>, which print the
   <SPAN
CLASS="APPLICATION"

   supports options <TT
CLASS="OPTION"

> and <TT
CLASS="OPTION"
