** COMMAND:  test-alert
**
** Usage: %fossil test-alert EVENTID ...
**
** Generate the text of an email alert for all of the EVENTIDs
** listed on the command-line.  Or if no events are listed on the
** command line, generate text for all events named in the
** pending_alert table.
** pending_alert table.  The text of the email alerts appears on
** standard output.
**
** This command is intended for testing and debugging the logic
** that generates email alert text.
** This command is intended for testing and debugging Fossil itself,
** for example when enhancing the email alert system or fixing bugs
** in the email alert system.  If you are not making changes to the
** Fossil source code, this command is probably not useful to you.
**
** EVENTIDs are text.  The first character is 'c', 'f', 't', or 'w'
** for check-in, forum, ticket, or wiki.  The remaining text is a
** integer that references the EVENT.OBJID value for the event.
** Run /timeline?showid to see these OBJID values.
**
** Options:
**
**      --digest           Generate digest alert text
**      --needmod          Assume all events are pending moderator approval
