        !             9: .sh DESCRIPTION
        !            10: For each directory argument,
        !            11: .it ls
        !            12: lists the contents of the directory;
        !            13: for each file argument,
        !            14: .it ls
        !            15: repeats its name and any other information requested.
        !            16: The output is sorted alphabetically by default.
        !            17: When no argument is given, the current directory is listed.
        !            18: When several arguments are given,
        !            19: the arguments are first sorted appropriately,
        !            20: but file arguments appear
        !            21: before directories and their contents.
        !            22: There are several options:
        !            23: .s3
        !            24: .lp +4 4
        !            25: \fB\*-l\fR     list in long format, giving mode, number of links, owner,
        !            26: size in bytes, and time of last modification
        !            27: for each file.
        !            28: (See below.)
        !            29: .s3

        !            31: \fB\*-t\fR     sort by time modified (latest first) instead of
        !            32: by name, as is normal

        !            34: .lp +4 4
        !            35: \fB\*-a\fR     list all entries; usually those beginning with `\fB.\fR' are

        !            39: \fB\*-s\fR     give size in blocks for each entry
        !            40: .s3
        !            41: .lp +4 4
        !            42: \fB\*-d\fR     if argument is a directory, list only its name, not
        !            43: its contents (mostly used with

        !            60: option contains 10 characters
        !            61: which are interpreted
        !            62: as follows:
        !            63: the first character is
        !            64: .s3
        !            65: .lp +3 3
        !            66: \fBd\fR        if the entry is a directory;

        !            68: \fBb\fR        if the entry is a block-type special file;

        !            70: \fBc\fR        if the entry is a character-type special file;

        !            73: .s3
        !            74: .i0
        !            75: The next 9 characters are interpreted
        !            76: as three sets of three bits each.
        !            77: The first set refers to owner permissions;
        !            78: the next to permissions to others in the same user-group;
        !            79: and the last to all others.
        !            80: Within each set the three characters indicate

        !            82: execute the file as a program.
        !            83: For a directory, `execute' permission is interpreted
        !            84: to mean permission to search the directory
        !            85: for a specified file.
        !            86: The permissions are indicated as follows:

        !            88: .lp +3 3
        !            89: \fBr\fR        if the file is readable

        !            97: .i0
        !            98: Finally, the group-execute permission character is given
