/*
** COMMAND: finfo
**
** Usage: %fossil finfo {?-l|--log? / -s|--status / --p|--print} FILENAME
**
** Print the complete change history for a single file going backwards
** in time. The default is -l.
**
** For the -l|--log option: If "-b|--brief" is specified one line per revision
** is printed, otherwise the full comment is printed. The "--limit N"
** and "--offset P" options limits the output to the first N changes
** after skipping P changes.
**
** In the -s form prints the status as <status> <revision>. This is
** a quick status and does not check for up-to-date-ness of the file.
**
** The -p form, there's an optional flag "-r|--revision REVISION". The
** specified version (or the latest checked out version) is printed to
** stdout.
**
** Print the change history for a single file.
**
** The "--limit N" and "--offset P" options limit the output to the first
** N changes after skipping P changes.
