/*
** COMMAND: touch*
**
** Usage: %fossil touch ?OPTIONS?
**
** For each file in the current checkout matching one of the provided
** list of glob patterns, or all files if no globs are provided, sets
** the file's mtime to the time of the last checkin which modified
** that file.
**
** This command gets its name from the conventional Unix "touch"
** command.
**
** Options:
**   -g GLOBLIST    Comma-separated list of glob patterns. Default
**                  is to touch all SCM-controlled files.
**   -G GLOBFILE    Similar to -g but reads its globs from a
**                  fossil-conventional glob list file.
**   -v|-verbose    Outputs information about its globs and each
**                  file it touches.
**   -n|--dry-run   Outputs which files would require touching,
**                  but does not touch them.
**
** Only one of -g or -G may be used.
**
