DESCRIPTION

Utility program for fetching info from BUFR tables. Execute without arguments for Usage, with option "--help" for some additional info. See also <https://wiki.met.no/bufr.pm/start> for examples of use. It is supposed that the code and flag tables are contained in a file with same name as corresponding B table except for having prefix C instead of B. The tables used can be chosen by the user with options "--bufrtable" and "--tablepath". Default is the hard coded DEFAULT_TABLE in directory DEFAULT_TABLE_PATH, but this last one will be overriden if the environment variable BUFR_TABLES is set. You should consider edit the source code if you are not satisfied with the defaults chosen.

OPTIONS

   --partial    Expand D descriptors only once, ignoring replication
   --simple     Like --partial, but displaying the resulting
                descriptors on one line
   --noexpand   Don't expand D descriptors at all
   --bufrtable <name of BUFR B or D table>  Set BUFR tables
   --tablepath <path to BUFR tables>  Set BUFR table path
   --verbose n  Display path and tables used if n > 0
   --help       Display Usage and explain the options used. Almost
                the same as consulting perldoc bufrresolve.pl

Usage 1): Resolves the given descriptor(s) fully into table B descriptors, with name, unit, scale, reference value and width (in bits) written on each line (except for --simple). --partial, --simple and --noexpand are mutually exclusive (full expansion is default). Usage 2): Prints the contents of the requested code or flag table (named by the table B descriptor). Usage 3): Displays the bits set when the data value for the requested flag table is <value>. Options may be abbreviated, e.g. "--h" or "-h" for "--help"

NOTE ON --VERBOSE

n > 1 in "--verbose n" does not provide any more output than n=1, so demanding an argument to "--verbose" looks funny. But if not, sooner or later someone would type "bufrresolve.pl 307080 --verbose 1" which by Perl would be interpreted as if the arguments were "307080 000001 --verbose", which probably is not what the user intended.
