        !            51: .Nm Cap_mkdb
        !            52: builds a hashed database out of the
        !            53: .Xr getcap 3
        !            54: logical database constructed by the concatenation of the specified
        !            55: files .
        !            56: .Pp
        !            57: The database is named by the basename of the first file argument and
        !            58: the string
        !            59: .Dq .db .
        !            60: The
        !            61: .Xr getcap 3
        !            62: routines can access the database in this form much more quickly
        !            63: than they can the original text file(s).
        !            64: .Pp
        !            65: The ``tc'' capabilities of the records are expanded before the
        !            66: record is stored into the database.
        !            67: .Pp
        !            68: The options as as follows:

        !            71: Specify a different database basename.
        !            72: .It Fl v
        !            73: Print out the number of capability records in the database.

        !            76: .Sh FORMAT
        !            77: Each record is stored in the database using two different types of keys.
        !            78: .Pp
        !            79: The first type is a key which consists of the first capability of
        !            80: the record (not including the trailing colon (``:'')) with a data
        !            81: field consisting of a special byte followed by the rest of the record.
        !            82: The special byte is either a 0 or 1, where a 0 means that the record
        !            83: is okay, and a 1 means that there was a ``tc'' capability in the record
        !            84: that couldn't be expanded.
        !            85: .Pp
        !            86: The second type is a key which consists of one of the names from the
        !            87: first capability of the record with a data field consisting a special
        !            88: byte followed by the the first capability of the record.
        !            89: The special byte is a 2.
        !            90: .Pp
        !            91: In normal operation names are looked up in the database, resulting
        !            92: in a key/data pair of the second type.
        !            93: The data field of this key/data pair is used to look up a key/data
        !            94: pair of the first type which has the real data associated with the
        !            95: name.
        !            96: .Sh RETURN VALUE
        !            97: The
