** COMMAND: ticket
** Usage: %fossil ticket SUBCOMMAND ...
**
** Run various subcommands to control tickets
**
**     %fossil ticket show (REPORTTITLE|REPORTNR) ?TICKETFILTER? ?options?
**
**         options can be:
**           ?-l|--limit LIMITCHAR?
**           ?-q|--quote?
**
**         Run the ticket report, identified by the report format title
**         used in the gui. The data is written as flat file on stdout,
**         using "," as separator. The seperator "," can be changed using
**         the -l or --limit option.
**         If TICKETFILTER is given on the commandline, the query is
**         limited with a new WHERE-condition.
**           example:  Report lists a column # with the uuid
**                     TICKETFILTER may be [#]='uuuuuuuuu'
**           example:  Report only lists rows with status not open
**                     TICKETFILTER: status != 'open'
**         If the option -q|--quote is used, the tickets are encoded by
**         quoting special chars(space -> \\s, tab -> \\t, newline -> \\n,
**         cr -> \\r, formfeed -> \\f, vtab -> \\v, nul -> \\0, \\ -> \\\\).
**         Otherwise, the simplified encoding as on the show report raw
**         page in the gui is used.
**
**         Instead of the report title its possible to use the report
**         number. Using the special report number 0 list all columns,
**         defined in the ticket table.
**
**     %fossil ticket list fields
**
**         list all fields, defined for ticket in the fossil repository
**
**     %fossil ticket list reports
**
**         list all ticket reports, defined in the fossil repository
**
**     %fossil ticket set TICKETUUID FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**     %fossil ticket change TICKETUUID FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**
**         change ticket identified by TICKETUUID and set the value of
**         field FIELD to VALUE. Valid field descriptions are:
**            status, type, severity, priority, resolution,
**            foundin, private_contact, resolution, title or comment
**         Field names given above are the ones, defined in a standard
**         fossil environment. If you have added, deleted columns, you
**         change the all your configured columns.
**         You can use more than one field/value pair on the commandline.
**         Using -q|--quote  enables the special character decoding as
**         in "ticket show". So it's possible, to set multiline text or
**         text with special characters.
**
**     %fossil ticket add FIELD VALUE ?FIELD VALUE .. ? ?-q|--quote?
**
**         like set, but create a new ticket with the given values.
**
** The values in set|add are not validated against the definitions
** given in "Ticket Common Script".
