-Usage:
-      bufralter.pl <bufr file>
-          [--data <descriptor=value[+]>]
-          [--bufr_edition <value>]
-          [--centre <value>]
-          [--subcentre <value>]
-          [--update_number <value>]
-          [--category <value>]
-          [--subcategory <value>]
-          [--int_subcategory <value>]
-          [--loc_subcategory <value>]
-          [--master_table_version <value>]
-          [--local_table_version <value>]
-          [--year <value>]
-          [--year_of_century <value>]
-          [--month <value>]
-          [--day <value>]
-          [--hour <value>]
-          [--minute <value>]
-          [--second <value>]
-          [--observed 0|1]
-          [--compress 0|1]
-          [--remove_sec2]
-          [--remove_qc]
-          [--outfile <file>]
-          [--strict_checking n]
-          [--tablepath <path to BUFR tables>]
-          [--verbose n]
-          [--help]
-Options:
-       --data <descriptor=value[+]> Set (first) data value in section 4 for
-                        descriptor. A trailing '+' means that the value
-                        should be added to existing value. Use 'missing'
-                        to set a missing value. Repeat the option if more
-                        sequence descriptors are to be set. Example:
-                        --data 004004=-1+ --data 00405=50 --data
-=missing This will set the data value for
-                        first (and only first!) occurrence of these 3
-                        descriptors in every subset and every message in
-                        <bufr file> to the given value (subtracting 1 from
-                        the existing value for 004004)
-       --bufr_edition <value> Set BUFR edition to <value>. If the new edition
-                        involves some metadata not present in the old edition,
-                        some educated guesses for these new metadata are made,
-                        but you should also consider setting these new metadata
-                        explicitely
-       --centre <value> Set originating centre to <value>
-       --subcentre <value>
-                        Set originating subcentre to <value>
-       --update_number <value>
-                        Set update sequence number to <value>. Use the special
-                        value -1 to increment existing update sequence number,
-                        -2 to decrement it
-       --category <value> Set data category to <value>
-       --subcategory <value> Set data sub-category to <value>
-       --int_subcategory <value> Set international data sub-category to <value>
-       --loc_subcategory <value> Set local data sub-category to <value>
-       --master_table_version <value>
-                        Set master table version number to <value>
-       --local_table_version <value>
-                        Set local table version number to <value>
-       --<time_var> <value> Set <time_var> (= year | year_of_century | month |
-                        day | hour | minute | second) in section 1 to <value>
-       --observed 0|1   Set observed data in section 3 to 0 or 1
-       --compress 0|1   Set compression in section 3 to 0 or 1
-       --remove_sec2    Remove optional section 2 if present
-       --remove_qc      Remove all quality information,
-                        i.e. remove all descriptors from 222000 on
-       --outfile <filename>
-                        Will print to <filename> instead of STDOUT
-       --strict_checking n   n=0 (default) Disable strict checking of BUFR format
-                             n=1 Issue warning if (recoverable) error in
-                                 BUFR format
-                             n=2 Croak if (recoverable) error in BUFR format.
-                                 Nothing more in this message will be
-                                 decoded/encoded.
-       --tablepath <path to BUFR tables>
-                        Set path to BUFR tables (overrides $ENV{BUFR_TABLES})
-       --verbose n      Set verbose level to n, 0<=n<=3 (default 0). Verbose
-                        output is sent to STDOUT, so ought to be combined with
-                        option --outfile
-       --help           Display Usage and explain the options used. Almost
-                        the same as consulting perldoc bufralter.pl
-    Options may be abbreviated, e.g. "--he" or "-he" for "--help".
-    To avoid having to use the "--tablepath" option, you are adviced to set
-    the environment variable BUFR_TABLES to the directory where your BUFR
-    tables are located (unless the default path provided by bufralter.pl
-    works for you).
