-;; -b, --escape print octal escapes for nongraphic characters
-;; --block-size=SIZE use SIZE-byte blocks
-;; -c with -lt: sort by, and show, ctime (time of last
-;; modification of file status information)
-;; with -l: show ctime and sort by name
-;; otherwise: sort by ctime
-;; --color[=WHEN] control whether color is used to distinguish file
-;; types. WHEN may be `never', `always', or `auto'
-;; -D, --dired generate output designed for Emacs' dired mode
-;; -f do not sort, enable -aU, disable -lst
-;; --format=WORD across -x, commas -m, horizontal -x, long -l,
-;; single-column -1, verbose -l, vertical -C
-;; -G, --no-group inhibit display of group information
-;; --indicator-style=WORD append indicator with style WORD to entry names:
-;; none (default), classify (-F), file-type (-p)
-;; -i, --inode print index number of each file
-;; -I, --ignore=PATTERN do not list implied entries matching shell PATTERN
-;; -L, --dereference show file information for referents of symlinks
-;; -m fill width with a comma separated list of entries
-;; -n, --numeric-uid-gid list numeric UIDs and GIDs instead of names
-;; -N, --literal print raw entry names (don't treat e.g. control
-;; characters specially)
-;; -o use long listing format without group info
-;; -q, --hide-control-chars print ? instead of non graphic characters
-;; --show-control-chars show non graphic characters as-is (default
-;; unless program is `ls' and output is a terminal)
-;; -Q, --quote-name enclose entry names in double quotes
-;; --quoting-style=WORD use quoting style WORD for entry names:
-;; literal, locale, shell, shell-always, c, escape
-;; -s, --size print size of each file, in blocks
-;; --sort=WORD extension -X, none -U, size -S, time -t,
-;; version -v
-;; status -c, time -t, atime -u, access -u, use -u
-;; --time=WORD show time as WORD instead of modification time:
-;; atime, access, use, ctime or status; use
-;; specified time as sort key if --sort=time
-;; -T, --tabsize=COLS assume tab stops at each COLS instead of 8
-;; -u with -lt: sort by, and show, access time
-;; with -l: show access time and sort by name
-;; otherwise: sort by access time
-;; -w, --width=COLS assume screen width instead of current value
-;; --version output version information and exit
-
-;; By default, color is not used to distinguish types of files. That is
-;; equivalent to using --color=none. Using the --color option without the
-;; optional WHEN argument is equivalent to using --color=always. With
-;; --color=auto, color codes are output only if standard output is connected
-;; to a terminal (tty).
