 * Options:
 *  -f fd:   stat fd instead of file
 *  -g:   use GMT rather than local time for time strings (forces -s on).
 *  -n:   always print file name of file being statted
 *  -N:   never print file name
 *  -l:   list stat types
 *  -L:   do lstat (else links are implicitly dereferenced by stat)
 *  -t:   always print name of stat type
 *  -T:   never print name of stat type
 *  -r:   print raw alongside string data
 *  -s:   string, print mode, times, uid, gid as appropriate strings:
 *        harmless but unnecessary when combined with -r.
 *  -A array:  assign results to given array, one stat result per element.
 *        File names and type names are only added if explicitly requested:
 *        file names are returned as a separate array element, type names as
 *        prefix to element.  Note the formatting deliberately contains
 *        fewer frills when -A is used.
 *  -H hash:  as for -A array, but returns a hash with the keys being those
 *        from stat -l
 *  -F fmt: specify a $TIME-like format for printing times; the default
 *        is the (CTIME-like) "%a %b %e %k:%M:%S %Z %Y".  This option implies
 *        -s as it is not useful for numerical times.
 *
 *  +type selects just element type of stat buffer (-l gives list):
 *        type can be shortened to unambiguous string.  only one type is
 *        allowed.  The extra type, +link, reads the target of a symbolic
 *        link; it is empty if the stat was not an lstat or if 
 *        a file descriptor was stat'd, if the stat'd file is
 *        not a symbolic link, or if symbolic links are not
 *        supported.  If +link is explicitly requested, the -L (lstat)
 *        option is set automatically.
